Z:gnu-www-ja-license-list--8f7842-This license requires all reci/en

This license requires all recipients to proactively help the licensor enforce its trademarks. This is an unreasonable condition to place on users' rights, so the license is nonfree. It also has other practical problems: some of the requirements are vague, and it uses the term &ldquo;intellectual property&rdquo;.
