It's been interesting to watch the Signal arc. From tech darling to "why do they think I want this" / "time to move on to what's next".
For example, I would like to be able to log into signal from multiple devices, which currently isn't possible.
So, I could imagine switching to something like telegram (even though less secure) or matrix (even though a little trickier for non tech users), both of which allow me to do this.
Personally though, I'm still using signal, donating, and have converted a few people, I'm just speculating here.
