I didn't catch any of the SOPA congressional hearing webcast yesterday, but it seems like the powers that be who want SOPA enacted aren't that keen on listening intently to the opposition case.
Needless to say, SOPA is bad news. I'm unsure what the total consequences of the bill would be for software, the Internet, and innovation to a larger extent since patent acquisition and infringement defenses are commonplace anyway (like Apple vs. HTC/Samsung). I'd say the companies that do sell licenses such as Microsoft, Apple, Oracle, etc. see this as more of an anti-counterfeiting bill than anything that would potentially fatten their bottom lines again.
