[Trisquel-devel] Mozilla's trademark policy: Still a problem

Why not recommend Mozilla branded software like Firefox, Thunderbird, 
and SeaMonkey? As explained in our Free Software Definition 
<https://www.gnu.org/philosophy/free-sw.html>, all four freedoms must be 
available on both a commercial and non-commercial basis. Mozilla's 
trademark policy serves to limit Freedom 2 to gratis distribution only, 
making the software nonfree.

 From https://www.mozilla.org/en-US/foundation/trademarks/policy/


If you're taking full advantage of the open-source nature of Mozilla's 
products and making significant functional changes, you may not 
redistribute the fruits of your labor under any Mozilla trademark, 
without Mozilla's prior written consent. For example, if the product 
you've modified is Firefox, you may not use Mozilla or Firefox, in whole 
or in part, in its name. Also, it would be inappropriate for you to say 
"based on Mozilla Firefox". Instead, in the interest of complete 
accuracy, you could describe your executables as "based on Mozilla 
technology", or "incorporating Mozilla source code." In addition, you 
may want to read the discussion on the "Powered by Mozilla 
<https://www.mozilla.org/en-US/foundation/trademarks/poweredby/faq/>" logo.

In addition, if you compile a modified version, as discussed above, with 
branding enabled (the default in our source code is branding disabled), 
you will require Mozilla's prior written permission. If it's not the 
unmodified installer package from www.mozilla.org, and you want to use 
our trademark(s), our review and approval of your modifications is 
required. You also must change the name of the executable so as to 
reduce the chance that a user of the modified software will be misled 
into believing it to be a native Mozilla product.

Again, any modification to the Mozilla product, including adding to, 
modifying in any way, or deleting content from the files included with 
an installer, file location changes, added code, modification of any 
source files including additions and deletions, etc., will require our 
permission if you want to use the Mozilla Marks. If you have any doubt, 
just ask us at trademarks at mozilla.com <mailto:trademarks at mozilla.com>.

Debian has permission to redistribute modified copies of Firefox with 
the Firefox branding, Parabola GNU/Linux-libre (and every other distro) 
does not. These Parabola packages are still maintained as a result:
