It's basically impossible to not engage with any corporate products at all. It's trivially-easy to not engage with specific corporate products. I don't engage with Twitter, because I won't sign up and that makes it useless to me. I'm not missing out on anything I care about.
Just one example: Facebook is mandatory for school/university in large parts of Asia. You cannot trivially block them. They should be considered an utility.
How did facebook make its way into education like this? Can you explain to an outsider?
