Don't know if he's really trying to make the project seem active, or trying to score a certain number of commits, or if he's just really passionate about cleaning up that codebase all by himself.

I mean this person is German (their Github bio). Even if they're not a programmer, why don't they instead take the time to translate some of the many german source files to english, like Libreoffice did back in 2013[1]?

Yeah I don't think anyone is doing anything nefarious here, and I definitely don't want to accuse anyone of acting in that way. I have my own weird hobbies.
I still don't think it's in the project's interest to have these changes merged in, they just confuse the history & make it harder to track down relevant context.
Also, I read a lot of the diffs and even a bit of the dev mailing list, development is as slow as it gets but there is new code being commited.
