Google has a good link describing SOPA and PIPA, and why you should care. Lots of other sites have gone black. I would, but am feeling lazy and don’t want to muck about with CSS.
My major objections are two:
I accept that the Internet as it existed in the 1990s and earlier does need to continue to evolve and change. However, I object strenuously to changes that don’t preserve openness, flexibility, and end-user control of data. These laws remind me of gun control and cell phone laws – it’s already illegal to pirate copyrighted works, shoot people, and drive recklessly; making it more illegal isn’t going to stop the activity.
