In contemporary society you are usually quite the outcast when you say you don't do social media. You have the choice between being an outcast and being spied upon. Similarly for government spying in messenger apps: if you are an outcast who doesn't buy a smartphone or computer you are not affected.
I can count the number of assholes I have met on Facebook. It's 0. I only put people I like in the first place on it, and surprise surprise, I enjoy using it.
It's not the tool people, it's how you're using it.
