It looks more like they were just being a typical stubborn corporation. Some product manager got really attached to the name and they tried to hang on to it as a matter of course, because they're massive and feel they don't have to budge to anything. In the end, they caved to negative publicity, as any company in their position would.
They had the opportunity to own up to their mistake and seek the goodwill of the community. They missed that chance. Perhaps not "evil", but certainly worth some continued indignation.
My suspicion is it'll blow over pretty quickly, though, if for no other reason than there are more pressing issues keeping most open source developers awake as opposed to an already resolved trademark dispute which never even went to court. This was a good day, wasn't it?
