It could be argued, of course. But isn't it more likely that an article on Microsoft for Macrumors would be an appropriate place for apple fans to talk about its shortcomings and flaws?
Hum... no ? If you think the goal of the site is to praise Apple and bash the competition, you've missed the point by about 3 miles. A big userbase of Macrumors are not Apple "fans" as you put it, we're Apple users with an interest for the larger technology scene. I think you're looking for CultofMac or AppleInsider.
MacRumors is much more open minded in general.
