I did, a decade ago, all my must have contacts have long ago added Signal or switched. Those that cant be botherd mehhhh i cant be bothered with them either.

Sadly in my country no one uses signal, everyone used either WhatsApp or Telegram or Facebook messenger for everyday.
I would love to migrate if everyone in my country use signal or other FOSS messenger app, because I'm sick to see WhatsApp become more and more patronizing every single update.

Done.

Nah. I'll use SimpleX until another post quantum disposable addressing & self-deleting app comes along.

Jabber’s for praxis.

🖕 PSTNs

I'd do it but family won't. Whatsapp is Goliath it will take some doing to peel away users because of the family connections

Will consider that I'd they provide a non-electron version.

Nope I preefer to use WIRE.

Unfortunately Signal has less features, is less convenient, not as pretty and generally unliked by people who don't care that much about privacy, which means it will never gather the critical mass to be able to move completely to it. All my contacts use WhatsApp, it's basically impossible to escape.
