Possibly Amazon. They tend to leave acquired companies alone to manage how they prefer, apart from Bezos micromanaging how to cut costs and restructure logistics, which is often a good thing. Plus Amazon (like Microsoft or Google) also has economy of scale opportunities for hosting GitHub on AWS. I do believe Amazon would interfere less with what users like about GitHub than Microsoft would.
