Well as AMD could tell them having the best hardware doesn't matter for doodoo if you don't have the software to match it.However, the unfortunate thing is that they are doing it just at the time Qualcomm seems to be finally getting their # together, with their Nuvia acquisition bearing fruit and the debut of the new Snapdragon X series.
Between MS and QC there is more than enough oomph to promote WoA to all the app makers and game devs, but evidently they screwed the pooch on that despite securing exclusivity.
Even without a CPU to match Apple the platform is plenty enough to make a secure foundation for building games on, and if QC had put half the effort behind it that Apple have to get Mac app devs moving we would already be inundated with apps and games.
You see Android if something of a non starter for serious game devs because of how easily apps could be pirated, but Windows has a history of anti piracy/cheat software that need only be ported to get game devs interested.
