I've been reading his blog for a very long time (more than 18 months) and I've NEVER seen him not kowtow the official MS line. Try to find one post in his archives that does not parrot official MS line.
I have been in the software business for 25 years and been on the management teams of 5 startups. I have been at Microsoft less than 3 years and haven't drank the Kool-Aid. However, I don't buy the Microsoft is evil argument either.
I rarely write about Microsoft. In fact I write about Google and lots of startups about 80% of the time. That said, if you want to disagree with my point of view anytime...that is fine. It is a free country.
