Basically only Signal + Whatsapp.
> claiming they don't do anything for privacy.
Well, Signal is kind of a scam in that regard.
Mandatory phone number exposure? (or did they finally implement usernames?)
A joke of a "registration lock pin" instead a proper 2FA to protect against sim-swap?
They received $3 million from the open technology fund, which is a government sponsored fund for censorship circumvention projects. https://www.opentech.fund/about/congressional-remit/
tl;dr: Lots of claims, lots of support.. but very little to back it up once you scratch the surface.
people in this field tend go overboard with security when really nobody cares about what they have access to.
What did he have to say about Matrix?
If you don't uphold the principles all you have to do is wait until it bites you too.
What happened to "I disapprove of what you say, but I will defend to the death your right to say it."
Nothing. It still is the same fake Voltaire quote used to con overly idealistic adversaires into giving you some situational supprt against their better interest. No institutional actor ever followed it.
Considering how he's tarnished Signal, there is absolutely no reason for them or anyone else to back him up.
What will be very funny is the fact that Telegram is pretty much not encrypted (yeah ok, "secret chats", whatever sure) and now that investigators probably have access to Durov's phone, that lack of encryption might come back to bite him in the ass. Can't wait to know what they find and if they do find something, it might be interesting to see if he finally changes his stance.
