I was about to loose some time making a whole article to answer this, but a extremely biased writing does not deserve that much. Bad experience with Angular, got it, sad for you, but that doesn't mean companies don't have to choose their own poison (React, Vue, Ember, Meteor, Angular or whatever they choose to use, or worse whatever the architect states as the main framework). Had to rewrite your whole backend? Mmmm, I smell bad programming practices, lack of leadership or poor foundations, tightly coupled code here just means your backend was developed and thought ro work with a single frontend framework.

Anyway, articles like this just show us that Medium is slowly becoming the new DZone, poor arguments in every post, mostly clickbait, no editorial committee to stop "writers" like the author.
