Last week the official YouTube app for Windows Phone received a major overhaul. Version 3.0 of the app brought some awesome Windows Phone 8 features like the ability to play under Lockscreen, download videos for offline play, pinnable channels and more. It went from web-wrapper to awesome with the recent update. Google now wants the app removed from the Store for violating YouTube’s API and Terms of Service.

Francisco Varela, YouTube’s Director for Global Platform Partnerships, sent a letter to Todd Brix. The latter (attached/linked below) asks for Microsoft to remove the YouTube app from the Store by Wednesday, May 22. Not just remove the app, but also disable existing downloads of the app. Aka, the “kill switch”, which (as far as we can remember) has only been used once before.

Here are three strikes against Microsoft according to Google.

Allows users to download videos from YouTube

Prevents the display of advertisements in YouTube video playbacks

Plays videos that our partners have restricted from playback on certain platforms (e.g., mobile devices with limited feature sets)

Here’s a choice quote from Varela specifically about removing ads from YouTube videos:
