Re: If not GFDL, then what? (original) (raw)
The publisher couldn't legally sell the book without the CD (or 2(b) notice); however, anyone else could buy a copy from the publisher, remove the CD, and resell it. See the "first sale" doctrine.
But the reseller would be distributing a modified GPLd work (without "source"), so would be bound by the terms of the GPL.
