How is it ever legal to break into a business's property and secretly video the operations? You surely can't sneak into a factory and record their processes to sell to China. Is it only allowed when it's being used for protesting, not for stealing IP? Or only on farms but not in factories? What about trespass law? Non-disclosure agreements for employees? Are those invalid?
It is as if states enacted laws against graffiti bearing a particular political or religious message, with either a greater punishment, or broader definition of "graffiti", than existing graffiti laws. Yes, graffiti is already illegal; yet these laws clearly violate free speech and equal protection, since the punishment is different based on what message you are trying to convey with the graffiti.
