The Mozilla Trademark Policy is now at version 1.0. We’ve tried very hard to balance the need to maintain control of our trademarks as a sign of quality with the desire to allow the community to use the trademarks to refer to and discuss Foundation products and to describe their relationship to Mozilla/Firefox/Thunderbird.
The attitudes of members of the free software community to trademarks is far more varied than attitudes to both copyrights (generally good) and patents (generally bad). How free is a piece of software if you have to remove all trademarks before you can make certain modifications? Does it depend on how hard it is to remove the trademarks? Does it depend on whether the trademarks have a functional purpose? Is it still free if you have to change the name of the binary, or do symlinks make that question irrelevant anyway?
These are hard questions. But we are convinced that it’s possible to make truly free software and still have strong brand protection, and we hope this policy is a good stab at doing that.
