Neat idea, or, you could just tell them directly and be like "hey I'm not gonna respond here due to [reasons], come find me on signal if ya wanna chat"
People are usually more engaged when you communicate to them directly
I thought people had been moving OFF signal lately?
Personally, I’m on signal, but never signed up for a Meta property because, well, it was obvious from the start that they had bad privacy controls that depended only on corporate promises.
Some use open source alternatives since signal still has the off switch to your communication. I personally use matrix for over a year and its pretty good. But its not polished so you need patience and a good admin.
I think because simpleX is more open source, self-hosted, and maybe slightly more anonymous. Not sure how the usability trades off for that if at all because I haven't used it (I mainly use signal and discord)
It also doesn't seem to be a mass migration by any means, just that simpleX is a bit better if you are super hardcore about your privacy.
Most are staying, but there's a growing shift to simplex among privacy/anon focused people
Signal uses closed source and centralized servers to deliver all your messages. Some people don't like their communications being dependant on a corporations computer, and would rather maximize data sovereignty when possible.
phone number requrement is unacceptable to some people
If SimpleX makes bad choices it can be forked and self hosted, whereas we would be locked in with signal and at the compamys whims
