A lot of time was spent training people on angular. Angular being so big meant more training. I'm guessing our Tech Leads are more comfortable with React because it isn't a framework.

The main issue stemmed from research, development, and training costs from what I understand.

It's fairly simple to piece together a framework with React. I'm using React, Flux, React-Router and Superagent.
