You aren't aware of every little detail about the actions that companies perform that affects the products you use. You don't know everything about water treatment, energy, housing construction, civil engineering, etc. And you don't know about those things because you trust people who do know to do the right thing. That's how society works. That's how billions of Facebook and Google users are. Facebook and Google should get in major trouble when they mistreat their data (like the Cambridge Analytica scandal with Facebook), but you disliking the data they collect and/or their business model does not mean that everyone else will. I know full well the type of data Google and Facebook collect about me and I just don't care. There's plenty of people in the tech industry that don't care either.
