Comment 23 for bug 1167425

In https://bugs.launchpad.net/ubuntu/+source/fonts-ubuntu/+bug/1754804/comments/4 it is stated that "Canonical disagrees" that the license is non-free (even if I don't see a source for the claim). The comment might have some weight, as that package on Ubuntu is no longer marked as non-free.

Clarification on this would be welcome.
