Its definitely a scary world, safe to assume all your online activity could be hacked if so wanted. Just gotta hope its not wanted and that it doesnt become possible to do it on a mass scale (UK is currently pushing to ban E2E lol, and I know the EU has contemplated similar. If you do fall into the wanted category, face 2 face is really the only option. I know a lot of politcal/investigative journalists also constantly cycle and maintain burner devices but even thats a risk of just how long is a safe time before a device is considered burned.
