What bearing do those other things have on whether or not this person complied with RedHat's trademark requirements?
He may be an asshole, but that should have no bearing on matters of trademark law.
Disclosure: I work for Red Hat, am an occasional Fedora contributor, but I have no dog in this hunt.
Probably wasn't a community rule, but more of a guideline... and, I think that principle has been violated here. I'm unclear of the domain owner's standing within the community, but as I've read more... it doesn't seem very excellent.
I do believe there is a nexus of causality between community standing, and permission to use the trademark. However, just my opinion, actual trademark law may diverge.
