if somebody really has high income(and high risk) illegal scheme he will not use signal for very bad things.
more, llm can tell exactly do things outlined above.
so chat control is for small(small income) crime and control of ordinary citizens behave well. in this sence it will serve its purpose.
so what is purpose going for signal developers? why not they try to do same with webrtc standard and browsers and llms?
You can also get a physical SIM from tons of shops (corner shops, supermarkets etc) with no ID and cash lol
