Earlier EA using the @battlefield account posted a image with 26 game keys for Battlefield 4. While the games are for sale in Steam, the games are still being installed in the Origin loader.
Steam has been arrogant and not willing to negotiate with studios resulting in a plethora of rival loaders.
If anything EA got attention over their Battlefield series which has faded a lot as not many use the Origin loader compared to the Steam loader.
Crysis 3 was noticed but again it requires the Origin loader to play. Crysis and Crysis 2 have moved to Steam outright.
All of the keys are long ago redeemed. They were gone within seconds of this being posted.
