With all due respect, I am a native English speaker and I agree with the GP. I wouldn't go as far as the Wikipedian in question (I surely have far better uses of my time than to make many tens of thousands of edits over a trivial nitpick), but the end result does read better and I'd have a hard time justifying a reversion of such an edit. Also, considering that plenty of non-native English speakers read the English Wikipedia, there is plenty of value in the English writing in the English Wikipedia being maximally clear without sacrificing the intended meaning of the text. Dismissing feedback out of hand on the basis of "well the person giving the feedback ain't a native English speaker" misses the point of Wikipedia being a resource for everyone. Broadening this beyond Wikipedia, the English language itself "is comprised of" countless words and grammatical structures yanked straight out of other languages, often by non-native speakers importing features of their native languages for all sorts of reasons. Knowing this history, I hereby authorize non-native speakers to critique the language and elements thereof; it's just as much their language as it is mine, and they therefore have just as much a right to it as I do.
