My apologies for misstating this. According to the internet archive, he stopped complaining about this problem sometime in 2008, a mere four years after the raw sockets restrictions were added to XP.
Do keep in mind, however, that his entire reason for continuing to publicize this was because it allowed him to continue making foolish claims like "Microsoft Does Not Understand Security," and to pretend that the eventual restrictions (not removal) of raw sockets in XP were proof that he was right. They were not.
In fact, the entire issue was over his own misunderstanding of security. You can't secure a network by asking client operating systems to restrict their own behavior on some kind of honor system (guess what: the bad guys' computers will not have these restrictions). The use of raw sockets did not disappear and the internet still exists. The claim that this was "a tremendous threat to the global Internet" basically amounted to "the sky is falling and only I can see it because none of the other security experts 'get it' like I do." Which is entirely bogus.
