> I [...] have no idea what you propose
It's literally the last item in my list?
But to further clarify: I would like existing lawful interception laws to be extended to services like Signal.
Not in the sense that any EU country should be able to break Signal crypto (as ChatControl proposes, and which I think is an utterly ill-advised idea), but that competent law enforcement agencies should be able to demand unencrypted Signal communications from/to an identified EU party, for a limited time and purpose, upon a (reviewable) judicial order.
Most, if not all, EU countries currently have similar laws applying to telegrams, snail mail, email, telephony and whatnot. If you don't like those either, that's fine, but that's the status quo, and I would like to see that extended to services like Signal, as opposed to incompetently dumb measures like ChatControl...
