The key point is that this is just for the ISO image of the first
disc. The other disks they do not distribute the ISO images for, and
reserve the right to make discs from those images for themselves.
The first disc is just the OS, while the other discs include all the
packages, the full ports subsystem, etc....
So, they make four ISO images, and then explicitly allow the
distribution and printing of the first image by anyone who wants to.
The other three are restricted and only available from BSDi/WC.
