I said that I occasionally agree with his conclusions. I mostly don't. But I'm not the ultimate judge of correctness, and I can't give the final ruling on them one way or another (that's not how philosophy works). However:

Not tone but process. Yudkowsky may be correct in the same way that the pope may be correct (BTW, I find both to occasionally raise a though-provoking issue), or both may inspire (different) people, but that makes neither of them philosophers because what they do isn't philosophy. I'll put it another way: your grandmother may make you soup when you're sick and it may (or may not) actually help you, but that doesn't mean she's practicing medicine.
The mere discussion, however, of "tone policing/tone trolling" is very much in line with what Yudkowsky does, which may best be described as expressing a certain political ideology regarding science, philosophy, knowledge, public discourse etc.. Everyone, of course, is entitled to their opinions and their ideologies, but that alone is not enough to make them philosophers, even if they try to keep their arguments consistent.
