> Social media censorship is not a big deal because we don't miss what we don't know. For example, people don't care they can't use google, facebook, instagram, because we have our own social networks. Also, people know not to talk about political subjects in these platforms because it is in bad taste and we know how to self-censor.

This is exactly why people don't even care about their words being censored. I live in China and 99.5% of my friends and family just use apps and platforms that "exist" in China. Those apps will even censor your private chats. They learned to self-censor and think it's good for them and their family. They just accept the censorship.
