I don't know why inferno isn't more popular, I use a lot of html5 apis so for what I'm working on inferno is more useful to me than react or Vue. I'm doing webaudio so react native doesn't help me. Also inferno doesn't require me to enter into a patent agreement with Facebook and yet I get all the benefits of react from using inferno. Now if I were needing to use native APIs then I might need react native but then you have to balance that need with the potential license issues
