Two-way binding is amazing for smaller sites, but it becomes a nightmare for an enterprise-level app. Digests, and having to wait for the next event cycle is an incredible headache, especially when you have to write tests and modify values outside of angular control.

Add to that the frequent execution and performance issues with watches and we deeply regret having to deal with it now.

Add to that having to learn the painful guts around digest-related executions. Watches fire on init so you have to ignore those first calls. Tests are nasty because timeouts have to be flushed manually, and $q promises won't resolve until you call $apply, etc. It quickly became "WTF is going wrong internally".

Angular 2 is a lot better, but at this stage I think so many former AngularJS/v1 developers went the react/vue route and don't see any reason to return.
