If Google lifted or adjusted something contrary to a non disclosure agreement, and then incorporated it in to code -- brazenly made open source for all to see a month later, and those proprietary aspects are now to be found in widely and freely disseminated open source code... the mind boggles. How could that be settled without a tacit admission that the code in question is proprietary?
A defensive without prejudice and confidential settlement of a quietly brought trade secrets claim would be one thing. Patent infringement and public action has invited invalidation proceedings -- I think as TopFemaleExecutive warned?
