I have a sincere question: why would it matter if a company supports or doesn't support some specific right? If they are not in a position to infringe on that right, what does it matter? What if Costco says you shouldn't have any absolute right against self-incrimination? What if Auto Zone releases a statement claiming you shouldn't be able to worship the god of your choosing? Hell, most Christians say you shouldn't be able to worship the god of your choosing, if it isn't their specific god, and in their specific terms.
So, why does it matter? Do these corporations really have the power to affect your rights? Do you think your rights boil down to elections and campaign contributions and lobbying groups? I would say to you that if you do believe that, you already have no rights.
