winphoneappdev

Having done my fair share of windows phone app development (8.0, 8.1, 10) I can confirm. Microsoft incentivized app development, and paid top game development companies millions and gave them featured placements for their half-assed windows phone ports.

And then as a regular joe you would actually put in the effort* to get things working well. Then you would watch these bug-plagued big name 3-star ports appear out of nowhere and usurp you on the top free lists and search results due to their favorable placements. And then you would move on to a fairer market, and when microsoft stopped paying them, the big app developers did too (not that they ever updated or fixed the bugs on windows phone releases.)

* Difficult as windows phone was the only mobile platform not supporting openGL in hardware and the top sold windows phones were incredibly low spec.
