On its 10th anniversary, Signal’s president wants to remind you that the world’s most secure communications platform is a nonprofit. It’s free. It doesn’t track you or serve you ads. It pays its engineers very well. And it’s a go-to app for hundreds of millions of people.
Also just because there are no alternatives doesn't mean your default position should be we just have to trust whatever exists now because it's good enough. Or that we can't criticize it ruthlessly, distrust it. Call it out and as a result of that build perhaps the desire for something better, a fix as it were.
The evidence and history clearly points towards Signal being very suspicious and likely in bed with the feds. This is not conspiracy thinking. Conspiracy thinking is thinking that the country/empire that gave away old German engima machines whose code they'd cracked to developing countries without telling them they'd cracked it in the late 40s/early 50s, that went on to establish a crypto company just to subvert its encryption. That's done everything Snowden revealed has in fact changed suddenly for the first time in half a century for no particular reason and not to its own benefit. That's fanciful thinking. That's a leap of logic away from the proven trends, the pattern of behavior, and indeed the incentivizes to continue using their dominant position to maintain dominance and power. They didn't back down on the clipper chip because they just gave up and decided to let people have privacy and rights. They gave up on it because they found better ways of achieving the same results with plausible deniability.
Also why is everything "tankies" with you people. Privacy advocates point out the obvious and suddenly it's a communist conspiracy. LOL
Matrix and XMPP are not alternatives and are worse for privacy and security
XMPP is exactly as good or bad for privacy as the servers and clients you choose. It's a protocol, not a service. Unlike Signal, which is a brand/app/service package.
The problem is, you're comparing apples with orchards. Analogous would be: 'email is worse for privacy than yahoomail'. Plus in this scenario yahoomail only lets you send emails to yahoomail addresses.
