Licenses are a copyright concept, but this isn’t a copyright issue. You’re buying a copy of a game, and you should own the copy after the purchase (which of course, means the company who sold it to you shouldn’t be able to revoke your access at will). That’s the part that sony is apparently not willing to do. But copyright-wise, it would be a license either way, so I don’t think it’s a good idea to confuse people with only tangentially related concepts here.
