Exactly, that's my take too, surely there ARE some people at MS with half a brain, even if they are about 0.00001% or so it seems, but they get evened out. May I also add that if the corporate structure of junior project managers is one where mediocrity rises to the top and the good minds get squashed you get a MS situation. That is it's not only the suits lacking the vision but also the lower echelons not attracting enough creative people, and when by chance they do get someone in they squash him or her with their mediocre way.
I mean for crying out loud how can a new product ad leave the building with a "marketplac" error, surely someone must have noticed it and thought, damn we are going to make fools of ourselves again, why didn't they say it? They didn't cause they are in a corporate environment that fosters mediocrity and squashes any innovation to the point of complete ineptness, and where no one really cares if they come up with something decent even. "So, it's marketplac and not marketplace" they seem to think, "I am not going to put my head on the line for that, let's release the ad as marketplac, it's not like anybody is expecting anything really good from us in the first place anyway..."
To me Microsoft is officially retitled as Marketplac, that kinda sums up everything they are about: stupid, unimaginative and completely inept at implementation.
