But in the linked post he does not explain, why he does not maintain a F-Droid repository for people who do not trust google, nor why the original Signal Client does not connect to Signal Forks, even if they use everything the same. Security reasons? Ordinary smartphones are full of rootkits anyways, so someone using a forked Signal version probably is better of anyway, as he knows a bit more what he is doing.

So the base argument holds in my opinion: Moxies main focus is Moxie in control. And not making Signal the best and securely possible.

So I also use Signal, but as soon as Matrix gets stable, I am gone

Having multiple branded builds to choose from would be a terrible thing and would easily allow fake apps to gain traction.

> ... and if you rebrand he forbids you from using the official Open Whisper servers.

This seems pretty fair to me. Not only could you abuse their resources, it would greatly hinder their ability to make changes and respond to protocol-level security threats. They aren't in the API business, controlling their ecosystem allows them to make forward progress without concern for 3rd parties that they have no control over. And still there is the issue of 3rd parties abusing their server resources.

The F-Droid argument is the strongest and most evident among all. I don't trust Google, I don't trust Play.

The main point is, Moxie could take the wind out of the sails of literally all arguments in this page by publishing Signal on F-Droid but he just won't.

This alone is enough for me to lose trust in Signal.

They've already made the APK available directly on their website for over a year now.[0][1] It works just fine (albeit a little heavy on battery usage) without the Google Play Store or Google Play Services. What more do you really want?

You can get Signal from the developers, Play Store or Apple App Store. No where else is genuine, all possibly backdoored. Why dilute that message for the 0.01% of users who would use F-Droid?

Which is maybe why Moxie is encouraging people to rely on Google Play Store.

If you are so concerned about state-level actors that play store is untenable to you, signal and android on commodity hardware are probably not the solutions you want anyways.

It seems pretty odd to me to distrust someone because they aren't using the platform that you'd like them to use. Aren't there other issues with f-droid? You have to root your device to run it, allow third party code. Those are all security concerns too.

It was posted elsewhere but here's Moxie's take: https://github.com/signalapp/Signal-Android/issues/127#issue...

Re:I don't trust Signal by abawany on Thursday August 09, 2018 @03:11PM (#17727443)
You don't need root to run F-Droid, just enable 'Untrusted Applications' in Settings, which I think is what you meant by third party code. The core reason I prefer F-Droid is that apps on it are not bundled with Play Store APIs and thus you can run on Android devices that don't have GApps installed.
Re:I don't trust Signal by Hello71 on Thursday August 09, 2018 @03:34PM (#17727677)
> You have to root your device to run it

wtf. I have been using F-Droid for many years, and this has not been the case. as far as I know, this has never been the case, as Android has always had functions for third party app stores. in fact, even today, F-Droid recommends not using root for installs, since then you don't get the screen showing permissions.

> allow third party code

that's called running apps.

tl;dr nice FUD.

Re:I don't trust Signal by angry_octet on Thursday August 09, 2018 @08:26PM (#17729744)
'allow third party code' means code which is not signed. Once you tick that any unsigned code can run, not only the app you downloaded. Makes exploitation significantly easier. It would be better if Android forced you to explicitly select which code could run, but too hard for most users.
Re:I don't trust Signal by ficklepickle on Friday August 10, 2018 @01:10AM (#17730835)
Then you "untick" it until the next time you need to install something.

This is what I do on lineageOS. I don't regularly install new apps.

Side rant: This marketer-driven "install an app for everything" is a threat to the open internet and privacy. Usually the only reason is to extract more personal info.

Already, young people barely use a web browser. That appears to be the future. Now get off my lawn or I'll start talking about the war.

Re:I don't trust Signal by angry_octet on Friday August 10, 2018 @07:16AM (#17732292)
You might do it, but thousands wouldn't.

Android could undoubtedly be stronger in this regard, and in permission control, firewall, ad blocking etc, but it's not going to happen.

Apps wouldn't be so bad if they were actually sandboxed properly, but yeah, they suck.

I was interested in Copperhead OS as an alternative, but it seems to have fallen into a greed induced mess.

Re:I don't trust Signal by cannonedhamster on Friday August 10, 2018 @10:09PM (#17737893)
You just shot your own argument against his point in the foot. Thousands of people doesn't even make up a percentage point of the users of Android. Most people on Android use Google Play because it's sufficient against the threats that they need to it be sufficient against. Most people are okay with the risk/reward ratios that come with using commercial software because they then don't have to think about it. Signal provides a nearly turnkey level of protection above and beyond standard messaging in an easy enough format for most people to use.
Re:I don't trust Signal by angry_octet on Saturday August 11, 2018 @03:20AM (#17738726)
IDK what you're going on about. What is your argument?

I am arguing Play store is fine, and side loading is bad policy.

I argued that for every person who will take the time to micromanage permissions, thousands wouldn't.

So what are you talking about?

Most likely one of those, yes. Though on Android 8+ you can only give that allow-install from unknown soures permission to F-Droid.

Also both Copperhead and Fairphone Open ship with the F-Droid priviledged extension by default allowing you to kee that setting entirely disabled.

At least, it's not odd, if that usage and what it entails is the denominating part of the persona in this question.

Re:I don't trust Signal by lordlimecat on Thursday August 09, 2018 @06:13PM (#17729016)
Whats odd is calling a application "not secure" because it uses the platform's software distribution channel.

Here's a thought. If you are so concerned about the NSA that you think Google's cloud is a problem, why are you running the OS developed by Google?

Sounds like you're confident you (or the FOSS community collective) can spot cleverly hidden backdoors.

I'm not, and I find that position naieve. For the overwhelming majority of people who are not a cross between Bruce Schneier and Linus Torvalds, a threat model that tries to protect against the NSA and GRU and MSS pretty much requires avoiding anything with a network connection. If you have a smartphone, you should probably just use its default application store.

Re:I don't trust Signal by leshow on Friday August 10, 2018 @10:05AM (#17733343)

I can trust people that I think made incorrect technical decisions, because I can see that they made a decision for technical reasons and have different priorities and reasoned soundly.

What I don't understand is why he's not doing that in spite of the fact that he could still keep control over Signal easily. One minor modification of the app and a forced upgrade would do the trick and render the F-Droid copies useless. The competition has been forcing users to upgrade in this way for a couple of years now. So I don't understand what he's afraid of.

Re:I don't trust Signal by jethro_tell on Thursday August 09, 2018 @01:19PM (#17726234)
google, facebook, whats app, microsoft. Basically the companies that pay for signal end to end encryption in their chat apps.

There are, I'm sure, apps that are better, and that's never been moxie's goal. He's said it over and over that he'd rather have encryption for the masses than the perfect messaging app. It seems disingenuous to assume that he's acting in bad faith when he's clearly doing exactly what he said he wanted to do.

If you want to make the prefect, self-hosted, chat eco system, fire up that matrix server and invite your non tech friends to join. I'm sure that will work out incredibly well.

In the mean time, Moxie seems to realize that to accomplish his goal and make communication incrementally more secure for average users, he needs to go where the users are.

It's crazy to me that people still think that secure communication is a technical problem. We've had GPG for the competent for a long time. The hard problems in secure communication are about using the eco systems that are available to large groups of average users and still being secure.

Re:I don't trust Signal by xvector on Thursday August 09, 2018 @02:25PM (#17726982)
Pushing an app out to F-Droid is trivial. There is literally no defense for only using Google Play and unsigned binaries on his own website.

I published an app on F-Droid once: it is a very light-weight process. One gives them access to the open source repo where the code is with build instructions and they then take care of pulling updates and publishing new versions.
Re:I don't trust Signal by barbs on Thursday August 09, 2018 @06:55PM (#17729255)
That process can be more complicated than it seems.

I tried to publish my open-source game on F-Droid, but the build process involves building native components with a specific third-party version of the NDK toolchain, as well as shell scripts to move files around, so it never made it to the store.

"Having multiple branded builds to choose from would be a terrible thing and would easily allow fake apps to gain traction"

In this particular case, not likely. People who are into more secure communication do not randomly click on anything. They know what they are doing, or get it installed from people they trust. And if they don't - their fault. Not Signals.

And Signal can continue to work and introduce breaking changes whenever they want. They simply only support the official build of Signal. Any person using anything different, cannot complain, if things stop working. (they will anyway, sure)

And the ressouce-abuse. Can this really be a thing? I don't know in detail how the protocol works, but what can I do with the servers, I can't do with Signal anyway? Sending (encrypted) data from A to B. I can allready abuse that today, if I want.

> People who are into more secure communication do not randomly click on anything

I think you overestimate people. I told my wife to install Signal because she needed a password for something and it was way to complicated for her to remember. I know what the signal app is and could likely avoid fakes - she would not. I think it is often the case that only one party of the conversation is security minded, while the others just trust that person.

> And the ressouce-abuse. Can this really be a thing?

You know NTP, the protocol for sharing what time it is? That gets abused badly [1]. If you have an open service, there are ways it can be abused. This would without a doubt lead to DDoS-like resource abuse where lazy clients don't cache things properly and just hog server resources. There are ways to limit things like that- but they aren't always simple. Also, like I said before, Signal isn't in the API business.

Re:I don't trust Signal by hutzlibu on Thursday August 09, 2018 @12:55PM (#17725961)
People who do click on the wrong "Signal" probably clicked on many other wrong things, too. Their Security is not existent anyway, even if they accidently use the official Signal build.
Re:I don't trust Signal by zaarn on Friday August 10, 2018 @03:52AM (#17731447)
So because a user clicked on a wrong thing we should completely abandon them and ignore all their security and privacy needs?
Re:I don't trust Signal by hutzlibu on Friday August 10, 2018 @04:15AM (#17731541)
Nope, but we should not limit the freedom of other users, who know what they are doing, because of some, who do not.
Re:I don't trust Signal by zaarn on Friday August 10, 2018 @04:18AM (#17731556)
I heavily disagree. If we want to protect as much people as possible we will have to limit the freedom of some users to do as they want because other users will accidentally or intentionally abuse the freedoms given.

Not limiting freedom of the user because they know what they are doing at the expense of others is maximizing the protection and freedom of a small group, not society as a whole.

Even if that wasn't wrong, it would be a fatal limitation for a social app which relies on network effects. Even if you were actually super-humanly capable of not making mistakes you'd end up using the apps that everyone else you know is actually on.
