It's a rhetorical question. None of the leaks provide any evidence that Google actively cooperates with the NSA in any way. No evidence of equipment at Google data centers, no evidence of any kind of remote access for the NSA, other than the already existing legal channels.

The claim that Google had foreknowledge of PRISM, or worked with the NSA to build some kind of firehose for them is unsupportable given what we know, and is pure speculation on your part.

Thus, the claim of close cooperation with the NSA is frankly, ad hominem.
