I don't think this is so true. Angular's $resource has different goals and functionality than something like ember data. To me, Angular's $resource looks closer to Backbone's sync methods.

Things I don't see in Angular's $resource:

* Identity map

* Support for switching adapters (e.g. online/offline)

* Relationships

If that's the case, they don't care. Ember-Data is the datamapper pattern in Javascript.
