I'm the weirdo who always reads the privacy policy at the bare minimum. I've opted out of a lot of services/apps/games/sites because of their privacy policy over the years.
Look it is bullshit they can get away with this crap but right now we only have the existing outdated legislation to work with. The absolute explosion of how technology and social media impacts the world has changed RAPIDLY in the last 15 years. It was once quaint that Obama did reddit AMA or posted a tweet.
So my point is yes be mad but ultimately it is out responsibility to be proactive with the tools that we have, and that's privacy policies and ToS. Like you're skipping through the villain's monologe laying out every step of their evil plan then shocked at the consequences.
