I don't see the issue with the line being drawn at content that was eventually sold to Valve. Content made official is a pretty obvious line to be made; including anything more will only further the debate for "well then you might as well make this a contribution worthy of a reward".
Sure, they're already rewarded with fame and a cheque in their pocket. But it's only a little something else that's nice.
