Signal does other things which annoy me to the point I can't consider it as a viable option for me, my family and close friends. For a start, it wants a full access to contacts and if doesn't get it it pops internal notification about it - but that one is easily dismissible. But then, I keep a strict notification settings on all my devices and Signal doesn't like that and wants me to turn these on. Perhaps because they can't otherwise push notifications about donation - which also appears within the app.

People behind Signal have a very corporate approach to their app where a permanent "no" doesn't exist when it comes to user choice - all what you have is "not now".

Then there's linking devices; it's not permanent but temporary and devices are removed automatically after 30 days. You can't even log into your account with tablet any more - that was replaced with linking. Cross-platform synchronization - didn't work for me at all despite being a loudly announced success.
