This argument about "can't reserve any rights that you don't pass on" seems to be to be contrived - that is, they have constructed an argument for their position that is not rooted in the four freedoms they claim to be protecting.

Which one of the freedom do you claim it violates?

To me it seems that it is inline with the general philosophy that distributors have obligations. The authors any way have all the freedoms, unless they use GPL and become distributors ;-).

I did not say it "violates" any of the four freedoms, just that it didn't derive from any of them.

That is, in logic, saying "A does not imply B" is not at all the same as saying "B implies not A".

It derives from freedom #1

The need for the DRM-related words in the licence is derived from freedom #1: "The freedom to study how the program works, and adapt it to your needs".

If I get the software as part of a hardware+software system, but after modifying the software the hardware transforms into a brick, then I have not been given freedom #1 in a meaningful sense. It's like pulling the trigger and out pops a flag saying "BANG".

In the case of the Tivo, I might want to remove the spyware and add a "copy to my computer" button. Making these modifications and then running my new version of the software on anything but my Tivo will not fulfil my needs.

In the 1990s, to ensure that freedom #1 survived the distribution chain, the GPL had to require people to published the source of any published binaries. In 2006, the GPL also has to require people to give the recipient any codes or passwords that the distributor has made necessary to run modified versions of the software.
