Airbnb's decision to abandon RN is clearly due to engineering blunders and political nonsense internal to Airbnb, which has little to do with RN itself.
But if you look at all of the github issues for RN you will see that many of them are open/unresolved for weeks with hundreds or thousands of +1s only to have someone at Facebook mysteriously close them, leaving a lot of people in the lurch.
We're also seeing a lot of API and internal refactoring fromi FB rather than focusing on the ecosystem, which indicates that inside FB it is more beneficial to say "I sped up x by 10% in react-native" than it is to improve usability for the many using it as an open source library trying to get something simple to work as expected.
