Why do you keep repeating "not for profit". As some have already mentioned, ( http://news.ycombinator.com/item?id=1913237 ) it does not make brand name abuse anymore acceptable. Financial profit is not the only thing, there are issues of "social profit" as well, and those have to be earned too.
Make no mistakes, I agree that its a great service. I would use it myself if the outstanding issues are resolved. But as I have said before, helping yourself to someone else's brand and work isn't very ethical regardless of its legal status. My views about that wont change even if pg agrees out of politeness.
