They still agreed to sign that contract and therefore are liable for what they and activist on do about Destiny. I keep seeing people trying to excuse Bungie, saying it was activision, but both parties are equally involved

They can actually tell Activision to make a good game they need time. Look at dice. They told EA they wouldn't be ready so DICE said fine we will release a complete shit version and it forced EA to let them have their time for battlefront (thank god)
