The No Hiding theorem of physics establishes that information cannot be lost to the universe, even by falling into a black hole. Since information cannot be lost to the universe, by your defintion of censorship it is simply a fallacious concept.

Could you please write in a way that most people can understand? Thanks. I didn't understand any of it :-)

Some authoritative definition:

HW has never dealt with censoring the content.

No writing can be made unavailable or prevented from being accessed.
Once someone writes something, it stays permanently the chain permanently and can be accessed with a relevant tool (which are many open-sourced to choose from).

No censorship is possible.
