Forking isn&#x27;t possible when the code is not there, and when the company that created&#x2F;copyrighted the code is openly hostile to forks. By them releasing under MIT, this issue is resolved.<p>As for the manpower behind Microsoft, git has made it very easy to merge code from relatively similar source code - in the cases that they make large important changes, those can always be merged in, and usually without too much work involved.<p>The only way they could succeed with something like that would be for them to go closed-source again, in which case you&#x27;re still better off than if they never went open in the first place because you still at least have some code to work from.
