"A bit of a Palestinian"??
Seriously, Anonymous Coward, that doesn't help clarify things at all. It's going to mean vastly different things to different people. Personally I find your analogy's implications offensive, but I won't go into detail because that would be following that distracting path further out into the woods.
Second, you have a typo missing a pretty important word - it should be "Linus does NOT want to do this in ideological grounds".
Also it's not so simple as it being an ideological objection. Linus argues that a major kernel addition that only runs binaries specifically and individually approved by a commercial entity with a history of actively trying to destroy linux, is perhaps a bad idea. He even uses the phrase "requires a lot more thought". Sure, later on he gets more angry and forceful in his arguments, but I agree with his decision here.
Trust and past behavior matter in human and corporate behavior - especially in the installation of a new system to manage trust at the very lowest core level of the operating system. Microsoft is has not proven to be, in my experience, technically competent or worthy of trust.
