"We were spurred to write an update when Dropbox published this post about why they also decided to stop using a C++ library in their mobile apps."

I was about to ask why this was being re-published... and also makes me wonder about if there are use cases where C++ for cross-platform makes sense and has been a huge success. To make a callback to AirBNB when they ditched React Native, they made it clear that they weren't saying that mixing React Native and vendor-native code wouldn't work for everyone, it just didn't work for them.
