Earlier quoted context omitted.
Censor: Highly targeted and specific, usually along the lines of communication. Like Xi and Winnie the Pooh. The US doesn't censor(?) Blacklist: Broader, usually applied to products and companies. China blacklisted Facebook. The US blacklisted Huawei.
Every state censors things in some way, he difference is what is censored and how much impact it has obviously. Censorship can also describe private actions such as Twitter/Facebook refusing some ideas, and is that case is vastly vastly present in every country.

*That is to say, I could perfectly well create some new social network messaging app that specifically does not allow any posts about honeybees, screwdrivers, or Turkey. The government could not prohibit those topics.
