Well, I kind of feel that I have to repost my comment on this old thread[1] with regards to the government of Egypt blocking Signal application:
"Isn't it "weird" that they chose to block Signal app and not the signal-protocol based Whatsapp?
If Whatsapp really implements the same kind of security and privacy measures that Signal does, why is Whatsapp allowed to continue operating?
If signal is preventing them spy on users and they ban it, is in't it safe to assume that Whatsapp is NOT preventing them spy on users, so they let it operate? Wouldn't you expect Whatsapp to be also targeted, especially considering the broad user-base it has compared to Signal?
Yes, I know they had blocked Whatsapp in the past, but they didn't block it now. Which means that something has changed in the relationship of the Egyptian gov and Whatsapp since 2015."
