I need you to explain either how Android/Linux) is less freedom-denying than
MacOSX/BSD.
Google's additions to Linux are free software. They do not deny our freedoms
in any way. Parts of Mac OS X include BSD code and are proprietary. They deny
our freedoms.
Google has to distribute its additions to Linux under the GPL because that is
Linux's license ant it is a copylefted license. Apple can sublicense
FreeBSD's code because of its permissive license.
When developing a program that does not reuse any code, the developer has no
restriction on the choice of the license. If she has no ethics, she makes her
software proprietary. The license of the operating system on which the
program runs cannot impose any restriction on the license of the program that
runs on it. The two works do not share anything. They are merely juxtaposed.
It is like putting aside a Picasso painting and a Van Gogh painting:
Picasso's copyright on his painting cannot impose any restriction on Van
Gogh's painting (or vice versa).
I do not know how to be clearer.
