Take a closer look at the use case.

The two first users (the one making the derived database and the one
unzipping it on a FTP server) both distributed the license. The problem here
is the direct link to the modified database and the CTO never seeing the
license text. The first user could of course have put some kind of notice in
the header, but then again he might not.
