Money and competition. Disney and Warner Bros are huge competitors. I don't think its a coincidence that they both bought up the 2 biggest comic companies in the world in the exact same year (less than a month apart).

...because they could. They buy Marvel and when it does well... Disney gets the benefit. In other words the competition turns into just another profit.
