First of all, this guy continued answering and asking questions since he published this article, so I guess he changed his mind about deleting his account. http://stackoverflow.com/users/2189331/jdevlin
Secondly the italic bits about how he should be allowed to delete questions because he created the content make no sense. All SO questions and answers are collaboratively created so he can't claim ownership.
I agree the moderation is out of hand, and it should be easy to delete your account (but what's this about a link that "got misclicked")?
