After my old "smartphone" went off, I can't communicate anymore with friends on PC, as both #signal and #telegram force me to scan "QR" with mobile device. I don't want to depend on a smartphone anymore!
I took some time testing different options and I'm now bringing my friends to #xmpp - stable, reliable protocol, you can use any clients you want either on PC or phone, and allows easy encryption and calls!
After moving from twitter to #fediverse, it is time to desert centralized apps, people!
