I agreee with much of your analysis, but I'm tempted to downvote since this seems potentially very mind-killing due to its political nature.
Although I did not consider this to be dangerously political when I posted it, the negative karma may indicate that others agree with you. However, the lack of angry comments would seem to indicate that this isn't of the mind-killing variety.
Power however is not restricted to corporate entities. Individuals can also wield the power of money, position and influence. By this argument they should also be forced to endure greater transparency and accountability.
And indeed they are!

The Electronic Privacy Information Center (EPIC) has filed a amicus curiae brief in the case.
The brief makes legal and philosophical arguments for privacy as an important human right, and that it is not a corporate right, and does not need to be. It also contains a number of scholarly references on the topic.
I find the legal arguments against a corporate right to privacy convincing. Corporations in our current legal context are intentionally organized to provide certain types of public accountability.
However, I am not convinced by the philosophical arguments for restricting the right to privacy to individuals.
To summarize the utility of an individual right to privacy, as discussed in the brief:
A right to privacy is necessary for individuals to enjoy the feelings of autonomy, control and security, which are important for healthy cognitive development. It protects the seclusion needed for experimentation, developing identity, establishing intimate relationships, and for making meaningful choices free of ex-ante manipulation and coercion. It provides the opportunity to structure life in unconventional ways, freeing a person from the stultifying effects of scrutiny and approbation or disapprobation. It helps to avoid embarrassment, preserving dignity and respect, avoiding harm to social development and growth. It helps to prevent the appropriation of a person's name or likeness. It sets the balance of power between a person, and the world around them.
To summarize the philosophical argument against a corporate right to privacy:
Corporate entities are incapable of experiencing hurt feelings.
