I can't say I agree with the Republican Study Committee on many things -- among other things, their leadership is responsible for holding the budget hostage to pursue more tax cuts for the 1%. (At least they're willing to discuss cutting the budget for the military.)
There is a strong conservative case to be made against modern American copyright law: it's a big-government handout to Hollywood that grants artificial monopolies, interferes with the free market, stifles innovation, and is clearly not what the Founding Fathers intended when they wrote the Constitution.
I'm not optimistic about the Republican leadership, or the Democratic, picking up the baton on this one. But I think it's a pretty big deal that people are actually talking about it -- and that some Republicans still remember that what "conservative" actually means isn't just "tax cuts for the rich".
All the major copyright landgrabs of the past couple of decades, from the DMCA to TPP, have been bipartisan efforts by lobbyist-owned politicians, with as little input from the voters as possible. SOPA/PIPA showed that while their support among politicians may be bipartisan, their opposition from an informed public is nonpartisan.
Even if nothing comes of this right away, I'm sure we haven't heard the last of it. Kudos to any politician willing to speak truth to power on this subject, regardless of party and regardless of disagreements we may have on other issues.
