Since implementing EME, I'm not sure Firefox is critical for an open web, since by almost definition, EME isn't open. As a practical matter I can understand why they chose to implement it (though that was not without controversy), but let's not fool ourselves here.

that's an interesting point to consider. I wonder what would have happened had they not done it? Would it have accelerated the decline? Or would it have been enough to get services not to use DRM? I'm not sure, but I think FF may have just dropped to irrelevancy faster had they not done it.
