[PS4] Second machine user can't play

[HEC]

Why would it be unacceptable? It's like this and always been. You should have researched prior the purchase. It's up to the game developer to decide if they'll allow multiply accounts on the same PS device to use the game or not, that fact that many do doesn't mean that all must do so. There are other games which works the same way. You'll not get refund either so unfortunatelly need to purchase game again or play it on the account on which it was purchased.
