Back in May Microsoft were forced to remove their native YouTube application for Windows Phone, recently they re-released this app to comply with Google, however Google have again blocked the ad due to what they are claiming as a violation of their terms of service, only two days after Microsoft released the app.
YouTube explained the block with the following statement:
“We’re committed to providing users and creators with a great and consistent YouTube experience across devices, and we’ve been working with Microsoft to build a fully featured YouTube for Windows Phone app, based on HTML5. Unfortunately, Microsoft has not made the browser upgrades necessary to enable a fully-featured YouTube experience, and has instead re-released a YouTube app that violates our Terms of Service.”
EnGadget claim this could be due to Microsoft not being on board with developing a HTML5 based application, reverse engineering the a system to satisfy Google, however this means that Google can’t guarantee the correct ads will be served, and have revoked Microsoft’s API key.
Microsoft have responded with a somewhat long-winded response, which you can find here.
