gollark: We had Cambridge Analytica and a gazillion random other things, and yet people probably just go "hmm, this sounds slightly bad, but abstract and not really relevant to me, and besides all my friends are here" and completely ignore it!
gollark: It'll probably take a giant scandal ("Facebook is stealing your credit card information and using it to buy random people illegal drugs!") to make people consider moving, and you know what? They probably won't!
gollark: Though they're still reachable by SMS, I can't participate in their group chats or whatever, and I probably can't convince them to use Signal.
gollark: I already have a bit of trouble communicating with some friends because they're on WhatsApp.
gollark: I mean, so far, I'm trying to avoid cloud stuff by running most of my services locally, but I have to interact with cloudy stuff to actually communicate with people, and regardless of what I do there'll be all kinds of shadowy data mining going on.
