I dunno if Konami is eligible since it doesn't push out many "AAA" games.
Activision has topped EA in my mind. EA, I think, is trying to get a little bit better (see Titanfall 2 free DLC). Activision is just going for broke whether by selling games piecemal as it did with Destiny or embracing pay-to-win tactics with Call of Duty. I'd say Warner Bros. and Ubisoft are tied after that. The DLC fiasco with Mortal Kombat X was pretty shocking in its audacity.
I hate to say it but I'd also nominate Microsoft. It's running Halo into the ground and pushing micro-transactions like never before.
