Microsoft won't ruin GitHub. Windows's ecosystem need developers more than ever. Developers are on GitHub. They simply can't screw it up.
I think Microsoft has done this a lot in the past. Mobile is the standout example, but even the Skype debacle had some good intentions. Microsoft had a super fragmented ecosystem of "Windows Live", Office, MSN, Skype.. I think it was noble to try and unify everything under one login.
But they tried to push said login down the throats of unsuspecting Windows users (that more often that not didn't use that MS ecosystem but instead used Google's), and (IMO) ruined Skype's usability in the process.
I don't know what the _right_ way of doing it was, but this certainly wasn't it.
WSL is not perfect, but it's good enough for a lot of use cases if you're stuck on Windows.
When will MS stop taking money away from the developers by making Visual Studio priced with hefty charges?
I still can't believe they're just making a barrier to entry by charging people who are going to help their ecosystem better and bigger.
