PS4 account sharing IS DEAD ! well almost unless u want to play the game on another account which is USELESS to me...
Well, the way i see it, there is a way to beat that policy around.
As we have 2 options, Activate account on one ps4 and 4 different users can use that account (on that ps4).
2nd option is to share it on 2 different consoles, and not play it on any other account(on a particular ps4).
Now suppose (will be feasible only for games, which the shared member don' wana play online/coop at the same time), i buy the game (from a secondary account), play it finish it (on my primary account). Then deactivate that account from my ps4, give it to a friend, so then he can log in from that secondary account and play on his primary account.
Well, its just a way. Though i hardly used game sharing to my advantage on ps3, i was looking forward to it on ps4 by going mostly digital. They may change the policy in future, which is hardly unlikely, but i am an optimist.
