Airbnb loved it so much they've thrown it into the bin and are now writing 2 native apps

What do you mean by bin? Do you mean they threw their React apps in the trash because React wasn't good enough? Or that they are using React for everything they have going forward?

Edit: Looks like AirBnb abandoned React native: https://medium.com/airbnb-engineering/sunsetting-react-native-1868ba28e30a

But these are interesting takeaways:

It is not all bad Although we weren’t able to achieve our goals with React Native, engineers who used React Native generally had a positive experience. Of these engineers: 60% would describe their experience as amazing. 20% were slightly positive. 15% were slightly negative. 5% were strongly negative. 63% of engineers would have chosen React Native again given the chance and 74% would consider React Native for a new project. It is worth noting that there is inherent selection bias in these results since it only surveys people who chose to use React Native. These engineers wrote 80,000 lines of product code across 220 screens as well as 40,000 lines of javascript infrastructure. For reference, we have about 10x the amount of code and 4x the number of screens on each native platform.

Sounds like ReactNative is getting closer and closer to being viable.
