Most of you who know me know I don't like piracy. The argument that companies charge too much for movies and/or won't starve if you steal from them presuppose that people are entitled to movies and that stealing is okay if you steal from someone who's rich enough.
That said, I oppose SOPA because it was too invasive, too poorly thought out, and not effective. Not that I want it to be effective; the widespread piracy that happens now is a cultural issue, not a legal one. Besides, apparently piracy isn't significantly affecting movie revenues here in the US.
Of course, like a lot of new laws, the introduction of measures like SOPA and PIPA assume that existing laws are not enough when they are. That makes RIAA's complaints about Google abusing their power even more...shittier and ridiculous.
