Erm... are you sure about Bethesda?
IGN broke a story a while ago about how Bethesda properly screwed with the developers of Prey 2, Human Head, in order to try and lowball them and buy them out on the cheap. To summarise, they unofficially promised the developers a cash loan to help finance development, then went back on their word and arbitrarily started rejecting milestones. This meant the developers started running out of development cash, and couldn't finish the game. Bethesda then offered to buy Human Head for an extortionately low amount of money. Human Head instead went on strike, and ended up handing the game back to Bethesda to go work with a different publisher on something else.
The sad thing is, there's a rumour that this is how they managed to purchase Arkane Studios, the developers of Dishonored- bullying them into a corner, then buying them at an extortionately low price.
While Bethesda may not have the same allergy to new IP that other publishers do, there's evidence to suggest they're just as big a bag of dickweeds, if not moreso.
