Beer is an asshole who was hoping that he would get a strong reaction. He's apparently always on the attack with his "brand" of assholishness.
Fish is an asshole who should have been able to identify that he was getting trolled. His assholery at least seems defensive when it comes out.
Regardless of my appreciation for Fez as a game, I hope Fish does change his mind and come back to doing something he is clearly very passionate about. I don't always care much for what individuals are passionate about, but always have an appreciation for people that ARE passionate about something. Fish has that in spades. The industry/community is better for having a guy like Fish as part of it, regardless of whether people hate him or like him.
This is simply the downside of trying to do something impossible. I suppose they could have a program where people mail in their UMD's and Sony emails them back a stack of vouchers for each copy, but that introduces a bunch of headaches.
They will not make a 1:1 "free" cost for converting a physical UMD copy of the game into a digital copy because they have no way to guarantee that folks wouldn't simply pass around UMD disks since simply having one in your hands means a free digital version of it.
They might have been better off just not doing anything at all.
