Phft. Google could put a huge crunch in it simply by frontpaging the entire situation — with the reasoning that it is invalid precisely because of the Bill of Rights (and list the specific instances) — and if they really wanted people mad, they would close down gmail like lavabit did with a redirect to that info-page.
People would be mad and quick.
They are going through the courts, like good citizens. Stockholders frown on companies doing unlawful things, and Google is a publically held company.
