Does Libram not count? Why do you get to also demand a mature ecosystem? This feels like demanding that corporations build a product specifically because you want it. There are precious few markets where we demand that businesses provide a product that the market wouldn't naturally demand, and I personally don't think that a general purpose computing phone should be one of those.
This whole discussion also feels a bit disingenuous now that you've brought up FLOSS, since Android has never really satisfied FLOSS-advocate goals. So why would it matter to you if exec privileges are changed?
