I don't think that there's difference, just implementation details differ. Youtube was blocked in Turkey for many years because someone from Germany uploaded defamatory videos about Ataturk(illegal in TR) and it was considered protected speech and Germany & Google refused deleting those. The situation was resolved when someone copyrighted Ataturk in Germany and made Youtube remove these videos.

Besides copyright, especially among Americans, I find that its completely O.K. to censor content it is bad for business. A major one is censorship in order to be advertisement friendly but anything flies, even the guy owns the thing and can do whatever he pleases is good enough for many(slightly controversial).

This is a myth: in Germany, as in many other countries, copyright covers only specific expression; you cannot copyright either the name of a historical person or a topic of discourse. The videos were briefly taken down as an automatic response to a complaint, but it seems the complaint was not upheld and the videos were restored.

At the time, Germany had a law censoring insulting comments about foreign heads of state, but that only applied to living ones (and maybe only those in office at the time?) That law was repealed in 2018.

The videos remained blocked in Turkey, but on account of a specific law banning criticism of Ataturk, not copyright.
