> I think that, with killer features like breaking out of DRM, the market share could change.
That's not a killer feature to the market: I bet 99/100 people don't know what DRM is or what it stands for. They just care that they can watch videos or not.
For better or the worse the overwhelming majority of browser users don't know, care, or have any idea about how the internet is standardized, how DRM works, and why it matters to them.
