If you read all the comments, and not just the one from the person with the pseudonym “WHOIS” you will see that the comments run somewhat in favor of keeping Whois information public. As for Mr. WHOIS, the pseudonym nicely provides him the privacy to confess to doxxing people and remain unidentifiable. So the comments are indeed worthwhile, both as an example of the range and distribution of views on the subject and the use of a form of “privacy” to hide from detection. (Unless someone is advocating a “right to doxx”, that would seem to be a Bad Thing.) of course, he could be fibbing, and never doxxed anyone, but no way to know that....
Finally, I think reading the article is much more worthwhile than reading the comments, just as I think the views of Brian Krebs are much more worthwhile than those of Mr. WHOIS-who-mightormightnot-be-a-doxxer.
I suppose everyone is entitled to their sources of information, but I still ascribe to the caveat “consider the source”.
