The anus.com article is fairly easily explained:
In extreme metal, there are only two cults of personality: Chuck and Varg. Now, if you're a politico-metalhead guro like Mr. Prozak or any of the other half-baked cunts who can only see metal in terms of a dark and nihilistic political movement, it should be obvious which of the two you prefer. Once you put non-musical considerations ahead of the music - such as the belief system of the songwriter - you're sliding down a slippery slope where you really can only like a small percentage of what's put out. Now, combine that with the fact that Prozak, like roughly half the Death fan population, obviously doesn't like the direction Chuck took following Human, and with the feeling we all get when we see someone we feel is overpraised, and you've got all the means and the motive.
On the other hand, in the terms the politico-nihilists have written themselves into, they can't simply passively dislike something that potentially affects people in a philosophical, or whatever, way, which brings us to something I said elsewhere:

If I'm right here - and I like to think that I'm always right - somebody like Chuck's a threat, either because he shows how full of shit these people are, or simply because the cross on the 't' in 'Death' is slightly higher on The Sound of Perseverance (interestingly he didn't jump on the fact that 'perseverance' is a term from Calvinist theology, since he seems to be grasping at straws to discredit Evil Chuck with the awful, awful sin of Christianity. Tool) cover than it was on the one for Leprosy. Either way, Chuck's one of the hugest figures in the metal underground - so much so that he bleeds over - and a figure many follow and respect, so if he's saying something other than - actually, opposite to - what these Metaller Than Thou fucks are preaching, he has to be taken down a peg or two, no? Death fans are in the same group the socio-politico-metalheads want to influence, so he's a viable and necessary target.
If you read the rest of the articles on that site (and I have), you'll find that SR Prozak, while claiming that nihilism is not about forcing things into rigid definitions, refuses to accept any music that doesn't fit his own rigid definition of what metal is. Which is fair enough for him, but you don't love music if 99% of it fails for you, and should probably turn to criticism of something else (his social commentary, while in my opinion overly ethnocentric, has a lot of good points to balance out the fuckheadedness, unlike most of his metal criticism). Or harass a mother that just lost her son to cancer about little nitpicks like where the cross on a 't' is; they're both good options.
Chuck still stings. December's the cruelest month.
