We obviously stil have a lot to learn about PRISM... But with that said, I have some conflicting instincts & feelings about all of this and the company responses.
On one hand, I would think a very-visible CEO of a major corp would keep their name off of a press release, if the press release was a lie that they were compelled to tell by the government.
On the other hand, I feel like each company's response and their use of the exact same terminology ("direct access", etc) feels like a wink and a nod.
