Protection through obscurity. If the NSA needs to go through the legal process to access data, the chances of them looking through your data is much lower than if they had unrestricted access. The cost of data inquiry discourages data inquiries.

That doesn't really answer my question though. The problem is that Google is handing over data, not what method is being used to try and access that data.
