They wanted to take his creative freedom that was given to him in his contract and he was angry about it. He took their asses to court and won, but that's when bungie fired him and started acting like they were the victims. He even announced that one of the songs in the advertising for destiny wasn't one of his pieces. To put it simple say you ask me to make you an advertising campaign and we make up a contract where you give me full creative freedom then we meet when I have it done. When we meet you say "you did good, but there's this other guy and we're gonna use his campaign and I'm not paying you." I can actually take you to court because I did all that work and you put in the contract I had creative freedom over this whole project then you go with someone else's work.
