We don't know, contract work can be hell with clients being really picky and uncooperative.
Not to mention that they may have picked them despite the fact that they are not a good fit but were available. We can't assume that they are good with more scripted rollercoaster rides when they are mainly known for systemic games.
It can be hell but if your product consistently is subpar even with client meddling then that's not a problem with bad contracts and bad clients, that's a problem with you. And it's not like Marvel is known for being hands off so...
As a consumer, their work is literally the only metric we have to judge them by. No one is reading quarterly reports for developers or researching into whether or not their contract went well with some publisher or IP owner. If you are consistently releasing mediocre to sub-par products then you're going to be rightfully judged on that.
