What's the difference between having zero power and having some power but always caving when it's important for the open web with the excuse that if you hadn't you would lose users and have no say the standards committees?
I get your frustration, I felt the same particularly after the DRM fiasco, but at least in Firefox it's not enabled by default. I'd say that is an important difference.
More importantly, I think what's important is that there exist multiple browser engines because that forces Google to at least compromise somewhat, (agree to WebAssembly instead of just DartVM for example), not run completely unchecked, even if I agree with your core premise and I think Mozilla should fight a lot harder than it often does.
