Are you going to support the "Keep Android Open" Movement?

Mozilla, 

If you are truly committed to the open web, why aren't you committed to keeping Android open, allowing users to gain access to Firefox in the first place?

Mozilla did take a tentative step or two into open source OS development, including for mobile devices:

but the efforts were abandoned in favor of resource conservation for other Moz projects. As with any nonprofit effort, resource prioritization and conservation are non-negotiable, as limited funds only go so far. Still, the need remains.
