I am baffled any time I’m on facebook how horrid it is. Loads insanely slowly, won’t accept picture uploads at random, randomly doesn’t let you share to people in your friends group (it will just hide people for no reason). Such a terrible website. Sadly I have to stay on it for friends and music reasons (there is nothing else anyone I know uses) but man, it’s crazy how badly they want you to install their spyware app so you don’t use the browser version.
For me the main thing not letting me quit WhatsApp (and FB before that) are groups and distribution lists. My cycling club uses WhatsApp to share info about all events. They are not going to move 300 people to Signal because I don’t want to use WhatsApp. Same with climbing gym group. 30 people, everyone using WhatspApp. I proposed moving to Signal at one point but no one even knew what I was talking about. It was the same with FB, people would post announcements on FB and if you wanted to know what’s going on you needed an account.
