I'm at a point where I'm actually afraid to use any infrastructure that's not open source, and I think many developers/hackers feel the same. If I were to write a library/tool that lies more on the "infrastructure" side than the "product" side, I would open source it because I would be scared to depend on infrastructure that's not open source. Also, because I will get much better value out of it if people more talented than me took part in its development. If node.js wasn't open source, I wouldn't even bother looking at it. If I looked at it, I wouldn't use it, just because it's not open source. I wouldn't trust one company to do it right. But I trust the hacker community to make it rock.
