What do you see as the biggest danger to open-source software today? On the one hand, there's still a locus of resistance. Microsoft still maintains strongly the view that its business model, which depends upon concealing source code from users, is a viable and important and indeed necessary model. And so as long as a company that sells a billion dollars a week in software is in that sense fundamentally still trying to [fight] the free way of doing things, Microsoft remains a very dangerous party.
