From what I gather this is more often a business decision than an individual developer's decision. When a product needs to go mobile for the first time on two platforms you have to make a business decision: 1) You can grow the team to tackle both platforms in parallel. 2) You can have the team do it one platform at a time. 3) You can have the team do it one time. Every option has big trade offs in either cost, time or user experience. There's somewhat of a gradient there as well in terms of code reuse giving the options avaiable right now. React Native sits somewhere between 2 and 3. It's really a matter of context for the business. How much time you have? Resources? What does your target user expect? For a lot of B2B companies, there's just not enough value added to choose between 1 and 2 since you either take more cost or more time to market and your user just needs the feature not the best possible experience. For a lot of B2C, your product may already be born mobile and you need the best possible experience to compete.
