A week ago Google served Microsoft with a Cease and Desist letter, asking them to remove their new YouTube app from the Windows Phone Store.

The app famously does not serve any ads, gives access to videos which were marked not for mobile, and allowed users to download videos, all red flags in Google’s face.

Now it seems Microsoft is prepared to take the issue to court. In a statement to Wired a day before Microsoft is meant to remove the app, Microsoft said:

“YouTube is consistently one of the top apps downloaded by smartphone users on all platforms, but Google has refused to work with us to develop an app on par with other platforms. Since we updated the YouTube app to ensure our mutual customers a similar YouTube experience, ratings and feedback have been overwhelmingly positive. We’d be more than happy to include advertising but need Google to provide us access to the necessary APIs. In light of Larry Page’s comments calling for more interoperability and less negativity, we look forward to solving this matter together for our mutual customers.”

The statement certainly not apologetic and has no tone of regret, and there is no indication Microsoft is going to comply with the request.

All together now: Fight, Fight!
