OTOH, this kind of tech is a godsend for smaller shops and solo developers, where having two completely separate codbases (or three if you also do a web version) can be impossible.
Or smaller startups who need to support both platforms at launch. We're going through that right now and we definitely can't afford to pay for a java dev and a swift dev and a js engineer (me). We also can't afford the Dev Shop costs of both iOS and Android. and our customer base is split 65-35. React-Native is literally a gift sent from God to save us
