I actually think that he likes aerius less if it makes you feel any better. Well, based on my conversations with jude I'd say you're more than a little bit wrong about that statement. It has way less to do with head-case being competition and more about not being comfortable with some of the parties involved. And even more to do with the information that people have access to in threads here (think RSA) and how that stirs shit up over there.
Me, I don't blame him for not liking links to this site. It only causes him grief and in now way benefits Head-fi.
