It’s all about developer tie-in. It’s far too easy to move your stuff between azure and aws. Microsoft needs to create differentiation and barriers to migration and since github is heavily used by developers who use both azure and aws, it is the obvious attackpoint. “Well I use azure because the github admin interface makes it easy to deploy, you can’t do that to aws from github...” etc.<p>Now depending on how evil(tm) Microsoft intends to be, they will either just only focus future development on integrations towards their own stuff, or they will actively degrade github when you aren’t going Microsoft across the board.
