Is Microsoft preparing to open source the Groove Music app?

With the announcement that Microsoft is removing the OneDrive streaming feature from the Groove application, I can’t help but ask myself why. It seems like this feature would need little to no maintenance to keep working. So it makes me wonder if Microsoft is removing it in preparation for making the Groove application open source? The OneDrive streaming technology implemented in Groove may have some patented technology that cannot be shared. By removing it they can release it like they have done with the Calculator application and have the community contribute to the application going forward.

Otherwise, why would Microsoft suddenly kill just the OneDrive streaming feature and not just the entire Groove application? One would think that they lose nothing by keeping OneDrive streaming in the application. OneDrive is a pillar to Microsofts services going forward and other applications use it to stream music, but with their own implementation.

What are your thoughts? Is this a plausible reason why?
