I definitely don't condone people telling you to kill yourself, but the fact that you are consistently receiving negative responses in an otherwise friendly community should give you pause: you're missing a lot of clues. Unless you enjoy being ostracized like this, it might be time for a bit of serious introspection.
Note that I suspect you actually want the third one, in which case I suggest you avoid MediaWiki. Not because it's bad, but because it's almost certainly overkill for your use-case and there's way simpler, easier-to-setup-and-maintain systems with fewer moving parts out there.
I try to be positive here on programming.dev but someone gave you an incredibly thoughtful reply and you returned the favor with absolute disrespect. I think the only positive outcome here would be for me to simply block you and encourage others to do the same.
Not annoyed, but many other people understood what I meant, and your suspicion was not correct, although I really used name Wikipedia explicitly (also, the image is PNG, it has word Wikipedia, but Lemmy decided to not show it, but when I was attaching it, it was showing)
Since most of those are run commercially and don't make their data easily accessible, that'll be a much different process, I assume. You'll basically have to scrape them like any other web site, except you'll specifically be targeting the edit/source view pages. Then find a wiki implementation that has as close a syntax as possible to the one they use (that could be tricky ...) and upload there. So unless you happen to find some code from someone who wanted to do the exact same thing, I'm afraid this would involve quite some programming/scripting.
Also, someone may want a snapshot of Wikipedia, but not need to run a full copy -- like, they don't need article history and such. You can get that too.

I kind of regret that, because I don't like the proliferation of wiki syntaxes. Like, I'd rather have just one syntax that everyone could learn.
Oh, I'm 100% there with you on syntax. But having multiple pieces of software that support the same syntax seems useful.
Personally I've turned into more markdown kind of person rather than the traditional wiki syntax. And at least that one gained some level of standardization over time ...
This is the way! Kiwix website has all the goodies one could want, and can easily download Wikipedia in your language and in different formats. Highly recommend Kiwix! Also comes with Android app, and PC client to read the documents offline.
