I think for software companies to comply with the EU ruling they would need to have a mechanism for transferring registration keys from one user to another. After the original buyer transfers their key to a buyer on the secondary market, the original buyer would no longer have access to the software.
It's been awhile since I read that Oracle v UsedSoft ruling, but I think that the new owner is entitled to whatever updates are offered. If they were paid updates, (like upgrading from v7 to v8 for $20) the new owner would still have to pay the upgrade fee, of course. But if they were free updates, then they would be free to new owner just as they would be to the original owner.
From a software seller's perspective, I don't see the issue with this. If you sell one license of your software to a user, you have accepted that one user will consume one license of your software. If that license gets transferred to a different user then the original user has relinquished their license, which has resulted, still, in only one license getting consumed by one user. When you sold the software you committed to updating that one license of software that you sold, what does it matter who is using and getting the update for that single license? (Of course you don't have to give free updates to any users whether they bought your software on the secondary market or directly from the software developer.)
If you look at ProTools, they actually let user transfer licenses between each other. The licenses are stored on an iLok and users can transfer keys between one another. It's great because users can sell used audio plugins for protools or the actual protools software itself to each other. https://www.ilok.com/#!home
