No, I'm not (a lawyer might recommend to sue, hoping for a big payout, even if the chances of it happening are small?). I looked at the GPL text, and what Google is doing is really pushing the "If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means", but others have done the same or worse, and so far fines that are really painful for a large company are few and far between...
