As far as spying goes, the game has evolved to the point where it's not really embarrassing any more. Everybody knows that everybody does it, and there's pretty strong resistance to going public. If anything did get discovered it'd probably be used for disinformation or behind-the-scenes political capital if not just destroyed. Finding a box of electronics at the bottom of the sea isn't quite the same as capturing an enemy pilot in a spy plane [1] and it's gotten to the point that embarrassing yourself for being spied on is just as bad as embarrassing an adversary (or friend) for doing the spying. Plus, how are you going to attribute blame anyway?
Well, Russia did eventually exhibit the Ivy Bells one. And Google staff did react to news that NSA was tapping its traffic. I'm not arguing that cables aren't being tapped. It just seems odd that none of the major cable operators have revealed anything. But as you say, there's arguably resistance to going public.
I wonder how many reported cable breaks were in fact screwed up tap installs ;)
I would take with a grain of salt and publicity around espionage acts. Snowden's release is just about the only one I believe was genuine or not part of some back room dealings.
The first assumption is that any such announcement by any entity public or private is either calculated or forced with plenty of forces in the background pulling the stings. It would make the most sense that pieces of Google were in the know, being forced by secret orders, and begging to be able to feign outrage publicly to save face.
A person doesn't have to be a conspiracy nut to have reasonable doubt about any of this. Secret courts, secret orders, and massive NSA data collection are all general public knowledge. It's hard to believe there is any public disclosure that is not planned and carefully negotiated.
