Re: [Trisquel-users] Doom/Doom II on Trisquel

I once turned down an offer to write a book on Python programming because of  
this principle and the publisher's unwillingness to make the book available  
under a libre culture license.
The funny thing is that these proprietary books end up on the web anyway.
A semi-libre option might have been a solution (see my post above).
Personally, I fail to see how preventing commercial redistribution could be  
unethical.
