Fair Turnabout implies the situation is the same, but turned around. That is not the case here. Difference being that Linus is NOT out there behind a podium telling a crowd of people that "this is best brand New Version of Linux EVER, and it's totally different and better"
Without a figurehead idiot trumping up this update its just not the same thing. You can't really blame the Linux community for being interested in a update to their software can you? It's not like they are making grandiose claims or holding press large press conferences that this is "the next big thing" (like Apple and others routinely do for their basic updates).
