Anyone who wants to read his words still can.
Also, according to pg, it is and always has been perfectly fine to downvote people for disagreement: http://news.ycombinator.com/item?id=117171 http://news.ycombinator.com/item?id=392347 http://news.ycombinator.com/item?id=658691
I understand that HN allows downvotes of disagreement, even though in this case it buries the most relevant information.
To stay on topic I can't believe the guy still hasn't apologized. Judging by his attitude and replies he's probably too busy self-rationalizing about how he's right and if everyone else wasn't an idiot we would all agree with him.
Downvoting also has the effect of lowering the comment's position relative to other replies. No matter the color, the comment will appear below someone who gets a higher score, even though I can't imagine a more relevant comment than from the guy this entire thread (and post) is really centered around.
Zee's 'punishment' shouldn't come in the form of mass downvoting and censorship. His punishment should be publicity. Let the community see what he has to say and judge his actions, not his comments.
