How do we beat AngularJS in the developers mindset?

I used emberjs one year.

My boss always ask me, why we use emberjs?

Because in the SOA architecture, most of the third party service provider angular SDK not ember SDK.

Ex: LoopBack or Clouddinay.

So I need coding by myself.

I think this is a very important issue for businesses.

Emberjs is best, but I am unable to refute my boss.
