The difference between Wikipedia and Facebook is that Wikipedia content is under a Creative Commons license which allows the entire encyclopedia to be forked. The entire Wikipedia database is continuously mirrored to servers in countries outside of the US, so Wikipedia can be resurrected in any other country if the situation you describe happens. In contrast, any Facebook content would be lost due to adverse government action.

Asking people to stop using Wikipedia is like asking people to stop using Linux because the Linux Kernel Organization is based in the US (California). There’s no comparable non-US alternative to either project, and the projects can be forked to different countries by their contributors without any action from the projects’ managing organizations. If you boycott Wikipedia, you also play into the hands of Elon Musk and other agitators who are attacking Wikipedia in an effort to redirect the public to right-wing US media sources.

Finally, part of my point was that Britannica is not an improvement over Wikipedia, because Britannica is also US-based. This is the reason I mentioned that Wikipedia editors are mostly from outside the US.

The author claims to be vegan, but also says that they will “stick to eating eggs” (which are not a vegan food) because they consider starvation a form of cannibalism, which is absurd.

Britannica is headquartered in the US (Chicago) and most Wikipedia editors are not from the US, so I wouldn’t count out Wikipedia so quickly.

Trans women are women. The poster made a transphobic comment by falsely referring to trans women as “men”, which obviously disparages trans women.
