If they cared about privacy then they wouldn’t use a searchable public database like FB.

pass - password manager https://www.passwordstore.org/

rsync - provides fast incremental file transfer https://rsync.samba.org/

xmpp - the universal messaging standard https://xmpp.org/

matrix - an open network for secure, decentralised communication https://matrix.org/

retroshare - private and secure commmunication and sharing platform. RetroShare provides filesharing, chat, messages, forums and channels. https://retroshare.cc/

No rsync? No pass? I’d definitely have the xmpp and matrix protocols on that list with a few clients listed for desktop and mobile.

The need to wait for an SMS to register a new account and the potential for recaptcha loop (which I have experienced) is a serious downside to Signal. Something I never need worry about with xmpp, matrix or threema.

xmpp has a variety of clients for desktop and mobile. You cannot dismiss them all as having worse ux than signal.

The same is true for matrix.

XMPP.

Threema.

Matrix.

Had this issue with a gmail account about 7 years ago. It has/had 2fa. Haven’t used it much since then.

You sound like you haven’t used matrix in a while. I use it daily. It isn’t super slow to sync.

I use GrapheneOS but have zero contact with the so-called “community”. The project itself is awesome but as with many Linux/OS projects a lot of the people around it aren’t all the way there.
