We still don't have a quality definition of ownership. Example would be that the ability to edit the OS "hosts" file to prevent a device from accessing say "twitter.com" should be a requirement in ownership.
Owned / purchased content should not be able to be revoked. Such as Ubisoft locking your account and preventing you from playing the games you purchased. Rental and leased content would fall into the account locking ability by Ubisoft.
