Nobody decided that it's a crime, and it's unlikely to happen. Question is, what do you do with mandatory snooping of centralized proprietary services that renders them functionally useless aside from "just live with it". I was hoping for actual advice rather than a snarky non-response, yet here we are.

Which jurisdiction are you on about? [1] Pick your poison.

For example, UK has a law forcing suspects to cooperate. This law has been used to convict suspects who weren't cooperating.

NL does not, but police can use force to have a suspect unlock a device using finger or face.

I gave you the answer that exists: I'm not aware of any existing or likely-to-exist secure messaging solution that would be a viable recommendation.

The available open-source options come nowhere close to the messaging security that Signal/Whatsapp provide. So you're left with either "find a way to access Signal after they pull out of whatever region has criminalized them operating with a backdoor on comms" or "pick any option that doesn't actually have strong messaging security".

You're asking for a technical solution to a political problem.

The answer is not to live with it, but become politically active to try to support your principles. No software can save you from an authoritarian government - you can let that fantasy die.
