Sceptic and cynic, certainly.
The basis of the conversation is simply that if you put '(c) Forum Name' at the bottom, it sort of presumes that you're claiming copyright over *everything* on the page. Copyright law does not automatically make that assertion, as in I still own my posts by law, unless I specifically agree to something granting the forum the right to make some claim of ownership over them.
The reason this escalated how it did is because I've had a number of run-ins with that particular person where he'll ask a question to try and justify something he thinks is a good idea, I'll answer it with a brief explanation as to why it's not, he'll ignore me and do it anyway and then wonder why I don't have a positive outlook on him.
Or, as cited, he'll do only the first thing that comes to mind and doesn't want to do anything more. Like he's complained quite a bit about not being able to monetise his forum, but anything requires work on his part, he's not interested in (like talking to advertisers himself, etc, but he's the first to complain that Adsense doesn't pay him enough)
