I didn't really look into this law, but notwithstanding whether it's really as bad as the site claims, there's one really worrying effect of this: Congress just has to continue trying, and some point people won't care enough anymore to stop it. The SOPA protests were impressive, but I'm doubtful that people will manage to continue protesting like that with every new law that congress is trying to sneak in. A bit like the constant reporting in the news about cruel same wars makes people care less about it.
