The quote in context isn't nearly as damning as GP made it out to be. It seems to me that Hammond was answering tongue-in-cheek and only meant to emphasize that his focus was on Node.js alone: One more thing: Developers using IO instead of Node are, well, not invited. “IO.js, what’s that?” asked Joyent CEO Scott Hammond in response to my query about whether projects based on the fork would be able to enter. “This is a Node.js project for Node.js innovations.” I'm not sure I can take the criticism seriously after seeing the source.
