Sony hasn't banned anything of the sort, its actually quite the opposite, i'd like to see where that was said.
E3 2013: PS4 Used Game Restrictions 'Up to Publishers' - IGN
EA has stopped all their online passes but it is not because Sony or anyone made them and you can more than likely still expect them from other devs who want to or currently do.

E3 2013: PS4 Used Game Restrictions 'Up to Publishers'
Not much is changing.

Sony has confirmed that the digital rights management of PlayStation 4 software will be up to third-party publishers. Speaking on GTTV, Sony's Jack Tretton stated, "The DRM decision for third-party games will be up to publishers."
This clarification comes one day after Sony's E3 press conference this week, where Tretton stated that the PlayStation 4 "won't pose any new restrictions on the use of PS4 gamers." He continued, "We believe in the model that people embrace today with PlayStation 3."
Publishers of PS4 games, then, can do what's already done on existing PlayStation software: Limit or lock content behind online passes or redemption codes (or opt out of restrictions altogether), which differs from Microsoft's limited licensing of Xbox One software.
