The idiots at TechDirt have no idea what they're talking about. None of that is illegal. They're talking about campaign contributions (which they have a legal right to do) or buying legal services from their client to support the Attorney General's cases. They're not saying "Let's pay bribe money to the Attorney Generals hurrrr-durrr".
These companies are very wary of what's legal and what's not, and they tread carefully.
Meanwhile, Sony, as a private entity, has every right to interact with government officials privately, perhaps with legal support for their pet causes. Just because they're interacting with government officials doesn't mean it should be public. Your social security # comes from interaction with government, do you want that public too? How about your tax returns?
Sorry, but if you want privacy rights, and if you're against the NSA, you better make sure that EVERYONE gets their privacy rights, including people you don't like.
Privacy rights isn't just for nice people.
