Anyway, I'm not advocating the extradition of anyone. I'm just pointing out that your friend's putting his name on 2257 stuff isn't anything more than a practical decision and a matter of course for what you, yourself, have stated is his family business.
Are you asking "Should I announce at some big party, 'Hey! Here's Johann of the Bergen Bestial Brethren!!!'"??? Depends on (a) your audience, (b) your relationship with Johann, and (c) how badly you want to fuck his Sister. Beyond that, I don't know what to tell you, Your Grace.
