The copyright owner can make any declaration they want, including an inconsistent one. Often, that makes the software non-redistributable in Debian's eyes. In other cases, the declaration that commercial use requires a support subscription is phrased in such a way that it is clear that it is a mere marketing claim and not a legal requirement (MySQL AB's statements before the Sun acquisition probably fall into this latter cateogry).
