I hope it produces a "counter attack" from RN the same way the trend about moving from React because of its license made Facebook remove that patent thing.
React Native usage at Facebook is growing. We know there are issues around integrations with existing native code, and they've been the motivation behind the ongoing large-scale changes in the internal architecture (which started in the beginning of this year).
Once that work is done it should make integrations with existing native code much easier. You can see that some of the post's content directly matches the pain points listed by Airbnb and Udacity -- because we bumped into the same problems and are working on the solutions.
I have a pretty solid counter argument lining up to be published soon (less than 2 weeks, hopefully not too late). I feel that those who had such a bad experience are just doing it wrong.
It has to do with native navigation. What apps are all about.
