The hacker named "D" didn't really want to write "fuck" in a pop-up when he hacked Netscape.com.
But, he said, Netscape's staff (including manager Jason Calacanis, who was "being such a twat") had ignored his e-mails and his attempted news posts (which he submitted to Netscape and competitor Digg) about a vulnerability in the site's code. So he had no choice but to go ahead and hack it.
Yes, highest honors should go to the brave man who maturely demonstrated Netscape's vulnerability in front of all its users. Because, after all, better to slap a swear word on a high-traffic site than to post something more devious.
