Yes they are to blame at a certain level... They signed the contract.

My point exactly. There are two sides to every deal and for a deal to be struck both sides have to agree on terms. Some people blindly defend Bungie as if these are still guys making games in a garage just for the fun of it. Reality is, when there is lots of money on the line, artistic integrity goes out the window, and Bungie is complicit in that regard.
