Complaining about longevity of React Native and then recommending two proprietary, non-open-source competitors is, frankly, absurd. If Facebook ever abandons React Native we have all of the code and can continue to support it ourselves. If Microsoft or Appcelerator ever shut down their platforms for any reason, we're SOL.
While there are some valid concerns with using React Native, the productivity gain and community make it a more than worthwhile trade off.
