I agree with you, I would've loved to see some more arguments, but to play the devil's advocate, he did offer some reasons against react:

  JSX wants you to couple your view with the model and controller

  I could give you a lot of specifics—separation of concerns, coupling views with models, the focus on needless optimizations, the importance of supporting open standards—but I'm going to tell you a story, instead.

Ok, I agree, he didn't give any reason aside from separation of concerns and company bad, web components good.
