Signal only delivers a promise that their E2EE will be enough to make the information govts get useless.
Signal do more than just a promise. Their encryption techniques are available to see. You can confirm if it’s enough protection for you or not. Telegram are the ones making a promise. I’m not saying they’ve broken their promise (as evidenced by the arrest).
But it is just a promise when Telegram still has the ability to see messages. Signal can’t see messages and therefore don’t have to rely on a promise that can be broken (willingly or not). They instead rely on encryption, which appears to be far stronger than any promise could be.
For all we know, this is performative and the French government already has access to Telegram’s servers and can see everything. If they have access to Signal’s, oh well, they can’t see shit.
Christians regularly ignore the 10 commandments, the most basic of rules in their religion. Of course they’ll ignore the stuff that means they can’t eat tasty pork
