I don't think the author is mad by the actual comment. It's Microsoft's foul attitude and delusion:
They're undermining and stomping on the audience who made them successful. And at the same time, they have this misconception that Kinect (which is entering a market, four years too late) is going to be an over night success. The think it will yield profits close to, equal to or greater than of what they had with the hardcore market or what Nintendo has had with the Wii.
In other words, MS is basically saying "We don't need you "gamers" any more, because dumb ass soccer moms, non gamers and little kids will eat this shit up. We've milked you for all we could and we're moving on. Oh, and thanks for your cash".
But little do they know, with that attitude, the competition (read: Nintendo) and (in my opinion), how much a piece of shit Kinect is, MS is in for a rude awakening. Their arrogance is unjustified, and they are going to pay for it. When Kinect bombs, MS will come up with every excuse and reason known to man, besides 1) it came out too late and 2) it's crap. Then again, do you really expect a big corporation to come out and be honest about why they fucked up?
