Re: [Trisquel-users] Thunderbird

You can use, study, modify and redistribute Mozilla's products. It is 100%  
Free software but recommends non-free software. That is why Trisquel  
maintains its own version without this problem.

The trademark restriction tells that modified versions of Mozilla's  
applications cannot bear the same name as the original ones. It is perfectly  
fine. It is only enforcing the trademark so that Mozilla's products can be  
properly identified (the whole objective of the trademark law). The same kind  
of restriction applies if you want to sell Mozilla's application, i.e., you  
must rename them. As Brett Smith says, this looks abusive. I wonder what  
qualifies as selling though. You can buy many magazines with Firefox or  
Thunderbird included on the CD that goes with it and, AFAIK, Mozilla never  
has never complained about that.
