what is react responsible for? If you're referring to the explosion of SPAs, I think you should direct your blame to angularjs... React was just a better version of that revolution.

Agreed. React, imo, was a much better Backbone.js. Relatively lightweight primitives, composition, and JSX made building frontend applications fun without having to wire up everything by hand.

Did the makers of anuglarjs also have a conflict of interest? Or did they ruin the web just for the love of the game?
