My answer has my name on it. It's right there saying "kstrauser said these words". If I didn't say them, I don't want the site lying and saying that I did. I don't mind if someone fixes an obvious typo, or updates a URL that had bitrotted. That's fine. They're what I obvious intended to say. But I've had people add extra sentences or paragraphs, and oh hell no.
That was never a core principle of the site, at least not when I joined it before you. If it'd been an expressed core principle that people could edit my words, attributed to me, so that my user account ends up saying things I never said, I never would have signed up and not many other people would have, either.
