If you object, don't click "I agree" to terms of service that you don't feel comfortable with.
It's like a prisoner's dilemma. You can complain about how people always defect on you, but you're doing the exact same thing.
Meanwhile everyone you know clicks "I agree" and you are now excluded from communicating with them. What did this accomplish?
More seriously, it's like an act of civil disobedience. If everybody acted similarly, we would not have these problems. Most people won't wise up until their kin are personally harmed by one of these massive unaccountable institutions, and until that happens to enough people, you have to recognize that acting in accordance with your principles will not always be the most convenient path through life.
