My fear might probably be unfounded, but NPM is an integral part of the JS ecosystem. And given MicroSoft has .NET Core, I have a strange feeling that they'll concentrate on npm less.
This is independent of what Microsoft's doing with .NET Core. I'm excited about the work that they're doing, but this isn't going to stop us from making sure that npm is outstanding.
Sounds like it won't be shielded from the cult-like MS mentality, then.
