You are being misleading. It actually says in part:
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.

So if I give somebody a DRM binary and an unencumbered copy of the
source and build scripts, I'm fine.

There are plenty of circumstances where this might be useful: say, a
player application and a set of keys. Some not-very-useful keys are
in the source, and some very useful keys are on the DRM medium.
Alternately, many of the TCPA tools will make good use of this situation.
