Oh, I don’t know. If they did it wouldn’t be the internet, just certain services like Telegram. Politicians over here, like in other countries, have been grumbling over encrypted chat apps for some time. And different articles and politicians have been labelling the rioters as terrorists so I wouldn’t be surprised if there was at least an attempt or proposition for some sort of law banning or prohibiting any chat client that cannot identify sender and recipient in the near future.
