The Hollywood Reporter has a lengthy (for them) description of how big-studio executives' SOPA effort looks, in retrospect, more like Pickett's Charge:
"They didn't understand the politics of the Internet, the power of the Internet, the perception people had of the things they were proposing," says an aide to a congressman who opposed the legislation. "The MPAA and the different lobbying organizations are trying to do it old-school and by the book. They ran into new technologies, new strategies, new techniques. I imagine they're sitting around discussing how they got beat."
The MPAA's [Michael] O'Leary concedes that the industry was outmanned and outgunned in cyberspace. He says the MPAA "is [undergoing] a process of education, a process of getting a much, much greater presence in the online environment. This was a fight on a platform we're not at this point comfortable with, and we were going up against an opponent that controls that platform."
More concisely: they just don't get it. And they probably never will, even after they become irrelevant (see under: record companies).
