Google et al. said something, IIRC, like 'we do not collect and pass on any info to the NSA'. Technically true, but also completely irrelevant to whether or not the NSA was actually collecting data.
They didn't mention the NSA: http://googleblog.blogspot.com/2013/06/what.html That post is unequivocal, and is in direct contradiction to statements by the post like:
The Foreign Intelligence Surveillance Court does not review any individual collection request.
The FBI uses government equipment on private company property to retrieve matching information from a participating company
Which directly contradicts a statement here: http://www.wired.com/threatlevel/2013/06/google-uses-secure-ftp-to-feds/ Unfortunately, all such statements in the Post's article aren't on the slides; they are the Post's annotations on the slides, and the author doesn't provide any evidence to support them. Take from that what you will.
