While I can't argue the shortcomings of js, it's hard to not see most of the argument as a strong stance of statically typed languages that get compiled against those of dynamically typed languages that evaluate at run time. Both types of languages have their time and place and I wonder if bringing that discussion dilutes the discussion to avoid react native.
On the point of community versus big company support I can't help but observe what appears to be anti open source sentiment conveyed as fact. While many of us have seen fads come and go we have to admit the wild success and stability of many open source libraries without formal agreements to maintain them. Everything from Rails, to Django, to jQuery, and Linux distros. There is a caveat here that JS libs do seem to die out faster and have questionable quality but again plenty are also great.
I think the choice of React Native really boils down to understanding the platform and source. If you understand how React Native leverages the toolkits and interacts with the system I think you have the tools you need to make a good decision.
For me I prefer native development where I can easily control and limit dependencies. If I want to hit all devices or most I'll build a great responsive web app. At the end React Native is today NOT a production level solution that will cover android and iPhone devices, android is a separate toolkit.
My rambling is done I suppose. If anything can be gleaned from this it is to understand the risks and be mindful of the costs of adopting a new framework and dev environment. If you are careful, intentional, and lean on smart teammates for help you will be just fine.
