After consulting with Red Hat Legal, we agree that this is an acceptable
license for Fedora. That phrase is occasionally seen in older permissive
licenses, and it means "you can do what you want with this, and
$COPYRIGHT_HOLDER won't charge you any royalty" as opposed to "you can
do what you want with this as long as you don't charge a fee".

Just a fun little MIT variant. :)
