I don’t use Signal to talk to people I know only pseudonymously through the internet. I use it to talk to people with whom I would already share my phone number. That social graph can be ascertained a thousand ways already. I think it is worth pointing out as you do, however. If I wanted to attempt to hide the fact that I was contacting someone from the state, I’m not sure where I would start, but it wouldn’t be Signal.
You may not be, but many of us are. None of it is free, from development to hosting to administrating. That works okay for now, but might be a limiting factor.
Edit: I also thing community stewardship could work better than it does.
