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 media. 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 [...]". > The transparent and opaque copies problem is also an unacceptable burden > on distribution (DFSG#1, #3).

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 under the terms of Sections 1 and 2 above on a medium customarily used for software interchange". 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 me). Regards, César
