Signal is a non starter for me. Centralized, requires everyone that uses it identify themselves, and they can and will use it to shill their crypto tokens or any features they want and you have no say. Its no different than Whatsapp to me.
If I cannot host it myself if I want to, or use it anonymously if I want to, then its not sovereign tech and not worth a second of my energy convincing anyone to use, especially when sovereign alternatives exist.
Matrix is by far the most usable sovereign option so it is what I switched my personal network to.
