Surprisingly Telegram awfully good on that list
Edit: I forgot to add that I found something little of about that report where Signal hash to phone numbers are absent " Which clearly signal store it"! And on Threema FBI still includ it even though it’s optional and 99℅ of the user will not put their number.
I imagine this is the reason we’re constantly told not to use Telegram. US has no control over the app or the servers, and none of US agencies were involved in development of its encryption protocols.
Governments never give shit to matrix.org protocol, does that mean it’s worse than telegram?
The graphic doesn’t show matrix or xmpp, probably because there isn’t much they can do about them, especially if they aren’t hosted in the US.
As far as I know Matrix is sound. Probably just isn’t as big as Telegram yet.
