Just to make it clear. I'm basically
advocating the "interpretation" of existing
GPL along the lines of:

The most important thing is this:

A few explanatory comments:

1. A derivative of a GNU GPL Program is a
derivative work as defined under U.S.
copyright law. That said, the following works
do not constitute derivatives: an application
program running in conjunction with an
operating system licensed under the GNU GPL
(just as an application program running in
conjunction with Microsoft Windows is not a
derivative of Windows); or a device driver
running as a kernel loadable module in
conjunction with an operating system licensed
under the GNU GPL. These are meant as
examples only – the list is not meant to be
complete.

In a way, the CPL is basically a "clear version"
of the GPL.
