I won't stick around to find out, my time is too valuable and the competition is strong. For me, Github doesn't really have any distinctive features except that is was the biggest, and so most convenient. I suspect most people and organizations will be in the same situation.
I suspect the vast majority of people won't be bothered to move their stuff unless MS pulls a Skype.
If they bundle the pro version of github with office 365 - just like with Teams, the 365 bundle becomes even more compelling for organizations.
What is that? I think its ownership of the huge amount of computer programs (and not to mention the associated metadata of authors and their professional network). The editor and the client provide a continuous stream of samples ready to be drawn from the world.
I believe its in the owners best interest to keep this golden goose of continuously increasing source of computer programs in good health.
The thing that I didn’t understand at first was why did MS gave up codehub (Google had Code, FB never pushed phabricator that hard) only to acquire GitHub later?
There's an increased chance of Microsoft starting to behave like they own Git, and trying to make it a part of their "platform" with proprietary extensions like their Git filesystem hack.
