I think it has to do with how the project started, MMC was the first to have a (voted for) developer fee. The problem started when the Initial dev team pumped the price, drained the dev fee for a while, and finally dumped MMC on their way out. That, and at the same time, some jaded early adopters really went to town, spreading FUD, in this (and other) forums. Finally, the nail in the coffin was when Delinquency created a dedicated MMC forum away from bitcointalk.com. Although this move did give the new dev team more control over the FUD on the new "official" forum, we were essentially isolated from the bitcointalk.com crypto community. Not to mention that those that wanted to (out of spite) see MMC fail basically took over this thread, and the rest is history
