Based on this poll Who uses what - Blaze/Angular/React/Vue - Poll Angular is no where to be seen and Blaze is still THE dominant technology for Meteor.
Blaze (which is built on Handlebars) remains a very strong UI as it is essentially the DOM with little abstraction and will continue to have its appeal (Ghost and other packages use Handlebars).
Personally, I think this is a ‘how to make money’ approach. MDG is now focusing on the data layer and less on the Meteor framework, so the community has to step in. I am willing to work with @mitar and the rest of the community on this.
Also, I believe that as a platform, Meteor in itself will see less and less investment from MDG regardless (the UI layer won’t solve that). So the community will HAVE to step in, even for React and Angular.
Side topic: I have a hard time believing you can make money just hosting Meteor, we spun up a DO VM for Meteor (with Clustering built in) and another DO for MongoDB and had a very solid infrastructure up in no time. Add Nagios and you have maintenance. MDG’s model may need to be redefined. If I am wrong about this, then great! One less thing that keeps me up at night.
