The Free-BSD community would have really benefited from a heavy hitter like Yahoo being more than just users of other peoples work.
I'm afraid I'm drifting way off-topic here, but I'd like to correct this comment. Yahoo have done lots of good work for the FreeBSD community. Yahoo employ several FreeBSD committers and other people who have contributed to the project. Yahoo host and manage many of the servers that run FreeBSD's CVS repository, Web site, mail, package building, etc. Their staff seem happy to publicly state that their Web servers run on FreeBSD, as in this presentation. I consider them "more than just users of other peoples work".
