Why would you have the expectation of an implicit agreement? There is no implicit agreement, that's an unfounded assumption by the user.
I imagine they could completely shut down all unpaid gmail access at any moment with no legal implications (though I haven't read the fine print, and in that extreme case the courts would probably step in just to keep the country running smoothly).
What precedent is there to support your hypothetical lawsuit? I kind of disagree, they would just get a lot of negative PR.
If Google simply shut down Gmail, their stockholders would pretty much fire the entire leadership of the company. It would be professional suicide to approve something like that.
There would certainly be a change of leadership due to the change in the business that shutting down gmail would cause. The PR hit would be huge, and I'd WAG that majority rule would not be enough to keep them in place.
