Arguably the biggest concern with React Native is that it is controlled by a single entity, Facebook, and that they are not one of the leading mobile platforms who from a business perspective have strong incentives to ensure the future of their respective app eco systems.
Facebook's incentives with React Native are somewhat unclear. This is a big, yet often unspoken, reason companies are vary of depending on React Native for their mobile stacks. With more large companies such as Microsoft, and now Shopify getting behind React Native those incentives will have to please a larger group and should become much more aligned with mobile developer communities at large - and not just Facebook's desires.
If Shopify manages to play an active role in the development of React Native and expand the project beyond the sole control of Facebook then React Native will become a much more viable option for companies who for political reasons have refrained from using the technology.
