If those Windows Phone users want to watch said content, they can do so in their web browser.
> The latest numbers peg WP's marketshare at 3 to 10% in various countries. Assuming a one to one equivalence of users and views, content providers are losing ~3 to 10% of revenue because of Google's dithering on this
That assumes that those people will not watch that movie anyway (on a desktop, on a friend's phone, or on the WP using the browser) - which is a completely bogus assumption.
> I would assume both content providers and ad buyers would benefit if Google makes an official Youtube app or allowed Microsoft's version with ads in it. Am I wrong?
The would also benefit if Google gave a free android phone to all WP users so they can watch it. So? Google is not a charity. They set terms and conditions for implementing a YouTube app. There are tens of youtube apps for both iphone and android that abide these rules (not talking about Google's official apps here! see e.g. Jasmine on iOS).
Microsoft insists on not observing the terms and conditions, and then blames google.
> they would do what Amazon does with Kindle and have a proper app on every platform that lets them publish one.
There's no kindle app for Linux. Or the Raspberry Pi. Or the the BeagleBone Black. Or the Chumby. or my smart Vizio TV. And yes, I run all these platforms at home. Does that mean Amazon doesn't care about Kindle content? (incidentally, the Chumby, Vizio and Linux all have native apps for YouTube, and each of them has sold more units than the Windows Phone).
> The fact that they don't shows that the reason is all about Android and not about Youtube.
Next time, you should start with the facts and work out to a logical conclusion, rather than starting with a conclusion you want, and trying to fit the facts into it.
