>I think Notch is overreacting in this case because he's already supported Microsoft's platform monopoly with Minecraft on the Xbox 360 (which is completely closed), so this stance seems kind of contrary.

I only think it's contrary if you require people to have simplistic opinions. He wants an open platform when it comes to PC, but isn't that concerned about consoles. I figure he thinks that as long as he has one major open platform he can develop for, he's happy. Microsoft is making moves that suggest they want to move away from an open platform for the PC, so he's understandably concerned.
