I think the creator of a work should be allowed to unpublish it but only if they own it entirely.

If other parties own it they should be required to make the work available without interruption or barriers and at a reasonable price.

If a recording was left to rot in some archive to the point others have a noticably better copy you've failed the obligation.

Anything that broadly looks like buying rights for the purpose of destroying the work should be stopped.

Objections should be written down and burned in a special ceremony.
