Do you really think a homebrewed self-update mechanism is superior to the battle tested F-Droid?
Moxie has a complete stranglehold on the Signal system. You are completely at his mercy for all decisions affecting the platform

The solution is federation, like email has always been.
There are a couple of ways to solve this problem, which can be used in tandem. We can stop Signal from knowing when we’re talking to each other by using peer-to-peer chats. This has some significant drawbacks, namely that both users have to be online at the same time for their messages to be delivered to each other. You can still fall back to peer-to-server-to-peer when one peer is offline, however. But this isn’t the most important of the two solutions.
The most important change is federation. Federated services are like email, in that Alice can send an email from gmail.com to Bob’s yahoo.com address. I should be able to stand up a Signal server, on my own hardware where I am in control of the logs, and communicate freely with other Signal servers, including Open Whisper’s servers. This distributes the security risks across hundreds of operators in many countries with various data extradition laws. This turns what would today be easy for the United States government to break and makes it much, much more difficult. Federation would also open the possibility for bridging the gap with several other open source secure chat platforms to all talk on the same federated network - which would spurn competition and be a great move for users of all chat platforms.
Moxie forbids you from distributing branded builds of the Signal app, and if you rebrand he forbids you from using the official Open Whisper servers. Because his servers don’t federate, that means that users of Signal forks cannot talk to Signal users. This is a truly genius move. No fork of Signal4 to date has ever gained any traction, and never will, because you can’t talk to any Signal users with them. In fact, there are no third-party applications which can interact with Signal users in any way. Moxie can write as many blog posts which appeal to wispy ideals and “moving ecosystems” as he wants5, but those are all really convenient excuses for an argument which allows him to design systems which serve his own interests
Why do I make a big deal out of Google Play and Google Play Services? Well, some people might trust Google, the company. But up against nation states, it’s no contest - Google has ties to the NSA, has been served secret subpoenas, and is literally the world’s largest machine designed for harvesting and analyzing private information about their users. Here’s what Google Play Services actually is: a rootkit. Google Play Services lets Google do silent background updates on apps on your phone and give them any permission they want. Having Google Play Services on your phone means your phone is not secure.
Moxie, why haven’t you put Signal on F-Droid yet?
Truly secure systems do not require you to trust the service provider. This is the point of end-to-end encryption. But we have to trust that Moxie is running the server software he says he is. We have to trust that he isn’t writing down a list of people we’ve talked to, when, and how often. We have to trust not only that Moxie is trustworthy, but given that Open Whisper Systems is based in San Francisco we have to trust that he hasn’t received a national security letter, too (by the way, Signal doesn’t have a warrant canary). Moxie can tell us he doesn’t store these things, but he could. Truly secure systems don’t require trust.
