I get that this ruling is focused on the piece of paper before it's redeemed and it's really good that a sticker isn't enough to limit your ability to resell something.

I'm wondering about after someone has redeemed the code. Once someone redeems the code, they presumably have to sign up for an account and agree to a long terms of service, which is (to my understanding) more accepted as a contract. It seems like this ruling doesn't significantly advance the issue of digital ownership.
