Thanks a lot for the detailed analysis. However, I don't fully agree with it.
As far as I understand, the anti-DRM clause doesn't "restrict any party from
selling or giving away the software as a component of an aggregate software
distribution containing programs from several different sources".
Any party can still distribute a GFDL document, but only using some kind of
GPL could be considered to have a similar restriction, as it states: "You may
not impose any further restrictions on the recipients' exercise of the rights
granted herein." An DRM media can be considered as limiting the 3rd section
of GPL: "You may copy and distribute the Program [...]".

But it DOESN'T require to include the code, you can still provide it in a
webpage: "or state in or with each Opaque copy a computer-network location
from which the general network-using public has access to download using
public-standard network protocols a complete Transparent copy of the
Document, free of added material. If you use the latter option, you must take
reasonably prudent steps, when you begin distribution of Opaque copies in
quantity, to ensure that this Transparent copy will remain thus accessible at
the stated location until at least one year after the last time you
distribute an Opaque copy (directly or through your agents or retailers) of
that edition to the public."
A year after the last distribution could be considered onerous, but GPL is
more strict, as you must "Accompany it with a written offer, valid for at
least three years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be distributed

In my opinion they are ugly clauses that should be corrected, but they are
DSFG-free anyway. (Of course, I understand that somepeole doesn't agree with
