I think for quite a lot of time Node wasn't doing much. The rebellion formed IO.Js. But what they forgot is still IO.JS is fork of Node. Only people like us who follow Node closely aware of IO.js thgh. Node is still preferred everywhere. It can still catch up with all the new features like ES6/7.
The problem (for node) is that the kind of developers who would node.js at this point are exactly the kind of developers who are aware of io.js, at the very least, and quite possibly aware of the reasons for its existence (which don't paint node and its steward in a positive light).
