Wikipedia is an American outfit, owned by the American businessman Jimmy Wales. It doesn't matter which language it is in.

Calling a system that is 90% foss and public domain "owned" by anyone is a bit of a stretch. I can, fully legally, download all the text of Wikipedia for about 130gb and host it myself. Besides, Jimmy Wales is awesome.

Wikipedia does not practice what it preaches. Even the claim "that anyone can edit" is not true.

Wikipedia is open source software serving public domain content. Wales controls the main fundraising outfit and domain, but the rest is not his IP.

It's an oligarchy in reality and Wikimedia was having a discussion a couple of years ago about implementing the SDGs, which come from the UN and not the public (who are barely aware of them.)
