Last thing we need is another frontend framework, least of all one with bizarre design decisions made by a team with a bad track record.
I've worked with Angular for a few years now, and I find it really great. I can only imagine what the Angular 2 refactoring will bring. A framework focused around ES6? Count me in.
Furthermore, we actually need more frontend frameworks, because that's how things get better. Evolution via competition.
Why? I'm not sure have an existing one that satisfies every requirement anyone will ever have.
