Thunderbird was re-branded on Trisquel because of Mozilla's trademark terms
(specifically the part that forbids commercial distribution). The re-branding
of Firefox is mainly for this reason as well. I don't get the reasoning used
by the Debian team:[1]
> We are building our own binaries and not using Mozilla's "unaltered
binaries", so that clause (which BTW I hate and consider cause for the
non-free-ness of upstream binaries) doesn't apply to us.
Mozilla's trademark policy doesn't say anything about permitting use of the
mark with unaltered versions of Firefox you compile yourself, but the only
place where it gives permission to use the mark at all is for these
"unaltered binaries" that the author of that email claims is not applicable
to what Debian is doing. That just doesn't add up to me. I would imagine the
clause forbidding commercial distribution would apply to Debian's builds, or
that the trademark policy would forbid using the mark on the builds at all.
But they seem to be interpreting the policy as giving them broader
permissions, somehow.
