Well, they made Angular. That's a pretty good record in my opinion. Not that I agree with all their design decisions, but the framework works, is maintained, and helps a lot of people.

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.
