Er, you claim Google has power. What if Mozilla, Microsoft and Apple implemented EME but Google didn't want to, and then everyone stopped using Chrome for all of the reasons mentioned in this thread? Then, Google doesn't have power. Contradiction!
No. Google has power because it has influence outside of web browsers. Mozilla have basically no leverage - their product is at best highly competitive with a number of other choices. If Firefox becomes irrelevant, Mozilla as an organisation dies - no money to pay the bills. If Chrome becomes irrelevant, Google's still very much a functioning company.
Or do you think that because of Android or something, Google would be able to stop the DRM when every other browser/device supported it?
