I always hated EE. They were an early adopter of dark UI patterns, and it obviously made them vulnerable to less user-hostile competition like SO.
Looking at Microsoft's strategy I doubt they would care whether it runs on .Net or something else. They would look into integrating with Azure (lots of Linux) and GitHub (R-o-R) as well as SO Jobs with LinkedIn (Java(?))
SO will still be there but maybe it will start the journey of it's eventual slow death.
LinkedIn is making bank with its subscription tiers. So they’d do a good job, financially speaking, of doing the same thing with SO. Large companies and recruitment services will be able to buy premium subscriptions to see who is doing what on the platform. Professionals will pay $50/month to have better access and limit access to non-paying members.
EDIT: Oops. Now I know that Microsoft owns LinkedIn.
