nevermind, I read comments and understand now^^
McQueen had mentioned that he'd done a film for a republican candidate or senator or something. Some news frenzy involving that candidate threw McQueen and his new work to the forefront. It was found out that while he directed certain types of films, he lived a double life as a porn actor/director. His most recent release was a lovey-dovey one with Ed so people were interested in it and Ed both found his image known by civilians and of course other people who watch porn (when he begins escorting, he's extremely in demand because people are curious about the man with Glen – something told to readers by Chang who hates it all).
And Ed's life is ruined in the classic "being associated with porn ruins your reputation within your circle" way (you can read about it happening to other porn stars if you do a quick google).
Hope that helps.
Also, since McQueen is a shrewd businessman and because of how he looked at Ed and said "wish we could both just leave to somewhere far away" it's insinuated that McQueen knew what would happen / had a hand in it for publicity.
I don't understand the last chapter :( What was that porn with Ryan? and why did everyone suddenly see Eds porn? And why did people find out that Mcqueen was the writer of the movie? And why does that affect Ed? ^^ sorry but I'm confused
