They're not bigger than Google. And it's Google's browser and the open source Chromium project, so I'm having a hard time seeing how Symantec is going to get a judge to say anything along the lines of "I forbid any and all members of the Chromium project to commit anything to the codebase that would no longer treat Symantec issued certificates as before". Especially considering since plenty aren't under US jurisdiction nor necessarily employed by Google. Then they'd also have to strong arm Mozilla, Apple and Microsoft since they're rather likely to act too and at least the latter two don't disclose such changes until they've made them.
