I think that this article underestimate the ability of Linus Torvalds to manage the Linux developers community. Leadership, dispute resolution, technical choices, compatibility or new features, and teven flamewars. It's very difficult to be a BDFL.<p>The idea is that if Linux were not available, the open source community would have been working in Hurd and not in Linux. But without Linus perhaps the community could not exist (new member leave after a few quarrels) or all the effort is lost in complete rewrites.
