I know of more than one organization that have decided against Angular in recent years primarily because of Google's backing of the project. Skepticism of the big three (four?) tech giants is growing, especially if you've had some of your market carved out by them.
Yehuda Katz said something a while ago that stuck with me. He likened Ember’s community model to Postgres. That is, relatively small levels of support from lots of different organizations. I think there’s a lot of wisdom is such an approach.
