It's a response to people sperging out over silly things which isn't more acceptable just because it's a tech forum.

FWIW, "quit whiteknighting for the megacorps", when someone rejects a comment that happens to slight a corporation, is just as tired as their complaint no matter how effective "down with teh corporations!1" is on social media.

That makes as much sense as accusing someone of whiteknighting just because they happen to defend a female politician or whoever.
