just my personal opinion, but I don't think this initiative is a useful form of protest. It's fine for exhibitors to withdraw from the event, that could have some reasonable impact, but asking press to boycott it is rather absurd.
For a start, a big chunk of the mainstream press are owned by the same companies that are lobbying for these stupid laws, so do you think Newscorp's IGN/1Up and Viacom's Gametrailers/G4TV etc etc are going to not be there covering everything regardless of what everyone else does?
Even if all independent press pulled out, all it would do is actually increase the traffic those publications would get as the only sources covering gaming's biggest annual event.
There are some good ways of protesting SOPA/PIPA out there, but this is not one of them.
In other words you don't have the intestinal fortitude to make a public stance, not because of copyright, but the way they've gone about it. What happens when legislation like this ends up here, isn't this just another form of censorship or do you support the internet filter and no R18+ for games? Isn't it too late to shut the stable door once the horse has bolted?
BTW I've never been to 1UP, IGN, Gametrailers or G4TV.
