I've read Gruber for years, and it used to be a mix of "interesting stuff in the Apple world", "Kubrick/Baseball/BBedit/Applescript/typography nits" and "criticisms of Apple" (usually centred around lack of attention to detail, interface annoyances or not being faithful to the pre-OS X way of doing things).
As an Apple owner and fan, I enjoyed reading those intelligent criticisms. Clearly this has changed, but lets not go rewriting history.
The last line of his first blog post:
"But if it’s the latter — that is, if pro users are giving the finger to Mac OS X — things could get ugly."
I wonder why he felt more able to criticize them when they were "beleaguered" than now, when they're on top of the world. Possibly it's no more than being a crotchety OS 9 user thrust into the strange and uncomfortable world of early OS X. Some evidence of that here:

On the other hand maybe he's checked his stats and found that trolling pays better.
And just for fun here's some claim chowder from one of his early posts:
"a vaporware Apple-branded mobile “iPhone” is getting a lot traction. Go ahead and read it, but remember that it’s all bullshit speculation at this point."
