It's actually quite conceivable that there was a first-line response memo crafted by a NSA/government official, that was sent out to the companies in question.

It's actually quite conceivable that there was a first-line response memo crafted by a NSA/government official, that was sent out to the companies in question. What the NSA might not have expected is that the receivers decided to stick to the template so closely. It's even possible that the companies coordinated their press releases for the very purpose of raising questions. We shouldn't assume they are all isolated from one another. It's far more likely that there is some form of communication going on between them, or at least between the high officials. In essence, this looks very much like a coordinated effort to rebel against a gag order without actually crossing the line and putting oneself in jeopardy. Read between the lines.
