React Native is supported and maintained by Facebook.
Recently the developer environment of React Native have changed a lot. Airbnb, which have previously vowed to React Native, have decided to leave behind the technology in favor to native technologies. This decision might have unforeseeable reactions on the adoption of React Native, since Airbnb were one of the biggest IT companies to utilize the technology.
Meanwhile, other companies, such as Shopify, have decided to start adopting the technology in favor of two separate code bases.
Whether this is an economical decision or a matter of superior technology choice, is difficult to say, but nevertheless React Native’s support base is going through period of change.
