Great read. There are obviously lots of different issues here, but the biggest takeaway I have seems to be: Udacity wasn't building a single app that ran on multiple platforms. They were building 2 separate apps that each ran on a single platform, and there happened to be a lot of overlap which made React Native look appealing. It turned out that the overlap wasn't enough, or else the team would not have done things like ever allow a feature into the tree that didn't work on both platforms before merging (i.e. let the trees get out of sync). Useful to consider before you adopt React Native in another app.
