A badly made native app is worse than a well built react-native app. There are plenty of anti-patterns that will ruin your native app.

In stories like this its much more likely that they just got sick of refactoring a big ugly code base so got buy in to throw it all away and starting over and the justification is native. Wait like 5 years and there will be a new react-native corss platform app because the native apps have too much cruft. Assuming we still have human in the loop then.

Sure, but thats not an interesting observation unless there is something about react-native that makes those apps consistently higher quality than native apps.

On the other hand, like-for-like C/C++/Rust performs better than javascript in terms of CPU and memory use, so the null hypothesis is that re-implementing would , in fact, improve things. There's little reason to think a priori that the end result would somehow be worse.

I think they also got sick of supporting those open source libraries.
