This is almost certainly not the sort of thing that a different CoC would have made any different absent an absurd IMO rule such as "Do not criticize individuals, projects, companies, etc."

Rather, this is a case of where do you draw the line when something/anything makes someone uncomfortable enough to complain. Do you apply a reasonable person standard and perhaps tell that person "We hear you but we can't agree and we're not going to do anything about it. Sorry."? Or do you say "We understand that we can't tell you how to feel so we accept your complaint and will take action."(And then do so.)?

In practice, for many situations, especially community events tend towards the latter.
