I think your ad hominem and somewhat hyperbolic complaint would be more credible if you supplied more concrete examples of how Angular caused your product to be two months late. I'm not saying you're wrong. I'm just saying that nothing in your comment actually makes your point.
My team has made very effective use of Angular and far from making us late it has saved us considerable time.
We treat Angular not as an abstraction or framework but as a toolkit for doing the following:
* Extending the browser's built-in HTML and CSS with our own custom behaviour.
* Two way databinding between our application data and the DOM
* Architecting small testable / mockable components
For what it's worth, there are some angular-isms that I truly dislike. In particular, angular.module is a bug farm for early angular developers. Also, without ngmin, Angular's "provider" declarations is both noisy and error prone. The truth howerver, is that these are minor problems and are easily discovered and fixed immediately.
