I haven't done a whole lot, but I've also never had a bad experience editing on Wikipedia. I suspect most people who complain about getting stuff reverted on Wikipedia are mostly editing controversial pages. Which, yeah, discussing controversial stuff on the Internet is a recipe for having a bad time. The other strong possibility is they are lower quality editors than they think they are. You notice they almost never actually link to the reverts they are complaining about.

This could be true. But I saw it in histories of not controversial pages also. Some people feel they own articles they contributed to. Wikipedia made a policy against this because it was a problem.[1]

I noticed they said it was years before nearly always if they said when. And to find revisions of forgotten date in Wikipedia required more time than most people would spend for a comment. And anecdotal evidence changed beliefs rarely.

I am confident that my edits were high quality and improved the mathematical accuracy and clarity of the page.

unfortunately I was editing under my real name and I'd rather not dox myself so I can't link to the reverts. but the general area was in social choice / computational democracy. so if you scroll around the edit history of some of those pages maybe you'll get the picture?
