I know I'm gonna get butt-hurt for this, but because I'm interested in the subject, I'd like to play devil's advocate for a moment.
Before I start, let me make clear that this Billington guy seems like a total assclown, not just because of this incident, but because of everything I've ever read about him and everything I've ever read by him.
Also, blackmail? So not cool.
But with that out of the way, let's say that Movie Blogger "A" (I don't even want to use Billington's name in this example) learns that Universal will be showing a full, complete cut of SCOTT PILGRIM at Comic-Con. Let us also say that Movie Blogger "A" is not invited to the screening and has no real working relationship with Universal, but wants to report his "scoop" on his website.
From a journalistic standpoint, I'm okay with him doing so. The PILGRIM screening counts as news, and the blogger has the right to report it. And if the studio learns of Movie Blogger "A"'s intentions and tries to persuade him to hold the story for a pass into the screening, I'm kind of okay with that, too.
Keep in mind this scenario is somewhat different from a blogger threatening or blackmailing a studio, but similar enough I figured I'd throw it out there for discussion.
It's also worth considering that if Movie Blogger "A" has hopes of forming a working relationship with the studio, blowing the lid off their Comic-Con plans may not be the best way to go about it. But that's for the blogger to decide. Got to weigh those pros and cons.
Lastly, I was a little surprised to see that Universal acquiesced and let Billington in. I know they didn't want their big secret ruined, but not taking a stand against this kind of behavior will only encourage more of it, no?
