The ECJ ruling only applies to Full Perpetual licenses of software. If these licenses came with other restrictions (could only be sold bundled with hardware, as part of a subscription, limited to use in academic settings only etc.) then they cannot simply be resold without those restrictions.

A lot of people in fact point to this ruling as a reason why more and more companies switched from perpetual licenses to subscription licenses. Without a full licenses there is nothing to resell and this ECJ ruling doesn't apply
