@Unlucky_Boot3467 This is an interesting read for sure, but I see no concrete evidence in the essay that suggests that Signal is insecure. Signal was never anonymous; users who have Signal accounts (myself included) are well aware that their Signal ID is tied to their phone number. If Signal were not offering the E2EE promised, that would be huge... but nothing in the evidence or the article suggests that that this the case.

To be sure, I think Matrix great. But I have to wonder at the agenda behind the article... indirect initial funding from the US government at the outset, even absent malfeasance on Signal's part, is bad, while direct current endorsement of Matrix by the French government is... good? to be clear, I consider neither problematic on their own, but there doesn't appear to be much in the way of logic behind that reasoning.

Overall, I'd like to see us move away from centralized control of communication.. and Matrix might in fact be that eventual solution. But that doesn't mean that Signal isn't safe for those who understand that it is not, generally speaking, anonymous to use.
