No, but it's very likely that they'll make decisions that'll alienate the community and thereby cause it's ecosystem to lose more and more relevance. It has done that with other open source projects they stewarded.
It depends on what you mean by "the community". If it's a community of contributors, and Google pulls it into a direction the contributors don't want, then they can fork it and continue contributing to it. If it's a community of users, then they have no choice but to follow whatever the contributors decide. I agree you need to have major contributors on board with a fork.
