This is good news for developers with Macs, and it has nothing to do with an option to switch platforms.
By doing this, Microsoft are legitimising bash as an OS feature for "developers who like unix". This has two effects on Apple:
1. It means they will be less likely to remove their bash CLI from a future OSX / iOS hybrid workstation OS nightmare that we all don't like to think about.
2. They will have to compete with Microsoft for customers who are "developers who like unix". Competition is good for us, the users.
