GitHub CoPilot Artificial Intelligence AI

Microsoft bought GitHub in 2018 for $7.5 billion. GitHub now operates as an independent entity within Microsoft, and the acquisition was completed in October 2018. 

Why did MS buy GitHub only to let it run as an independent entity?  I feel like I'm being encouraged to believe Death Jab Gates would not sh!t me.

Research Links

• GH: CoPilot – cost schedule – but isn't copilot the same name used for their OS nanny that wants to take an image of what you are doing?   
• Visual Studio is being pushed as the editor / IDE that is augmented by AI

Notes on Microsoft Ownership

• GAI: Why did MS buy GitHub only to let it run as an independent entity? 
• GAI:  is visual studio open source and if so can I download the code?
• Visual Studio Code – download / installation

Seems convenient for MS that you get ramped into MS editor and AI that will see all.
