While I agree with the basic tennets of Rick's argument, I would ask in
return: if not a comparison of the GPL to the EULA, then what? I see these
two licences as perhaps the primary exemplars of the FOSS and proprietary
worlds, and as such, are perhaps the only readily available agreements we
can contrast in this manner.

What I find quite surprising (and the motivation for my undertaking this
comparison) is that no-one else has done something similar.

You are correct. My ommission.
