In the past two months, Microsoft and Google have been bickering over one central issue: HTML5. The Verge has learned that Google is forcing Microsoft to build its YouTube Windows Phone app in HTML5, despite its own Android and iOS versions using superior native code. Although Microsoft has offered to build ad support along with making other tweaks as Google has requested, a full HTML5 app isn't currently possible on the platform.
The difficult thing here is that Google actually has a very good case; it's their API, their service, their rules. On top of that, YouTube publishers - big and small - need to earn money from advertisements too, and incorrect implementations make that harder. Microsoft's mafia practices regarding patents, extorting companies to pay for Android use even though Microsoft has contributed zero code to Android plays a role too. Lastly, Windows Phone is essentially irrelevant with 3% market share - it's not as if Microsoft ever concerned itself with minority platforms.
Still, all this does is hurt consumers, no matter how few Windows Phone users there are. Just work this out, please, you bunch of children.
