> Is a comment to the maintainer and waiting for answer sufficient? A comment may not be noticed by the maintainer, as the maintainer can disable email notifications for their own packages. You should email the maintainer if: * You want to ensure that the maintainer knows about the incorrect package. * You intend on fixing and adopting the package yourself.
If your intent is simply to tell others about the incorrect license, a simple comment is enough. Well, that's my read on the situation. --Jeremy
