Not according to Augery (angular chrome extension), but not sure if all evidence can be built out of the result.

However, mobile.twitter.com and facebook proper are using react. Along with Walmart.com and many, many others.

The biggest Angular app I've seen is probably grubhub, and there's some painful state bugs there... in fact I don't think I've ever seen an angular app (not using rxjs or redux) that doesn't have weird state management bugs.

I tried using Angular 1 when it came out and it seemed like too much work to learn for such a small benefit. I started learning React at the start of last year and have found it phenomenal. I am not comparing the two, let alone arguing in favour of Angular. I just thought with the swap to Material Design (and async loading data and components) in YouTube, that they were using Angular. Your opinion about YouTube using Angular (or not) has more citation and authority than mine, so I will assume in the future that YouTube does not use Angular (without certainty, of course).
