@qbe @ati1 @ondra @chatcontrol To be fair, as far as I understand chat control in it's current form specifically tries to legally pressure services from companies they can fine, not requiring "non commercial" stuff to conform since it will be harder to come after smaller, open source software. For now.
But there is a different precedent, Russia, which requires any service to give out private messages on formal request, and either sues local services or blocks foreign services for not complying, regardless if it's just refusal or if it's impossible because of e2ee. It requires a massive internet censorship apparatus to be in place and enforcement is selective despite that, but this is a real world example of such system being sucessfully introduced to a nation that had freedom of internet for long enough to see it as norm.
Which means, regardless of how absurd and delusional that idea of banning e2ee sounds, it is a real threat to your freedom as long as some individual in power has it.
