It depends what GitHub’s people want.
It is worth mentioning that GitHub is loosing a lot of money, so from a financial perspective I can see why GitHub would want to sell out to Microsoft.
It also depends what GitHub is for, if it’s a coder/geek inspired social network then I personally don’t think it would be good, as I would not feel to comfatable hanging out in a Microsoft controlled walled garden.
(… a digression)
For example I enjoy painting a drawing I have taken some photos of drawings I have done and shared them with friends on Facebook, but I wouldn’t want to use a big company like Facebook to collaborate with others on a hobby.
Alternatively if GitHub is for business and self publisining and earning money then Microsoft will aid in that regard - MS know how to make lots of money.
I personally always smile when I hear talk of good standards, proprietary interfaces to GUIs that companies own and control are kinda cheating IMHO.
So I wouldn’t go as far as stating that Microsoft are planning to Embrace/Extend/Extinguish Git, but for sure expect Microsoft to talk ad nauseum about how easy it will be to file a pull request in Windows/VS Code!
