Are you sure that this statement is true?
"your content can't be banned, censored, taken down or demonetized"
You should read Article 13 of the Terms of Service on Hive.
Also note that persistent down-voting can completely demonetise and even remove accounts from being viewed.
Hive is no different to any other social media platform.
It has controllers and censorship by the most wealthy.... much like real life, wouldn't you say?
