The problem is that people want to converge on one system, so opting out often isn't viable. I don't use Facebook, for example. But when my school makes an announcement, or creates some kind of bulletin board or sign up, they often use Facebook. Most people are on it. If I want to advertise a mobile app it is really hard without using Facebook or Instagram. You say "you can't just come and take it away because you don't like that person". This is not about animosity toward any person or company (or it shouldn't be). We have stopped people or issued government control when people are close to having monopolies over oil, monopolies over power, telecommunications, etc.
