I’m European using signal, I frequent in two countries very often (not neighbouring countries) and for the past two years I’ve noticed more and more people using signal.

Ditched whatsapp half a year ago and haven’t had problems. Some friends use both signal and whatsapp.

Not saying many in whole Europe use signal but it certainly is not only popular in US.

Edit: but not saying using signal will change anything if this bill passes. No matter what popular app we use we are going to have no privacy at all if this thing passes…
