Publishers, console makers, really anyone that thinks they can make a quick buck off a studio with a good idea will do all they can suck every dollar out of the game, not caring about the result to the gaming audience they're trying to sell it to. And it's only gotten worse as time goes on because publishers have figured little tricks like microtransactions to make even more money. The worst part is, now you need a huge budget to make an AAA rated game, so studios have to pray that these huge publishers like EA or Activision will invest in their ideas. The state of the market is really sad truly. Hopefully Bungie will be smart, and once they're done with this contract with Activision, they can work with some smaller, less money centric publishers or maybe do what Bethesda or CD Projekt does and self publish.
