I mean hasn't Depp also stated he won't work with Disney again even if they asked to have him back? I would imagine he feels like he got stung and thrown out once the accusations were made without the evidence / due process and wouldn't want to work with a company who basically disowned him without even trying to talk with him to address the situation and hear his side of the story. But as others have said it would be very tough for Disney to just never work with actors who have had drug or alcohol problems, they are rampant in Hollywood / with celebrities in general. Sure Disney has lots of clean celebrities as far as we know but it's impossible to expect every single person Disney works with to have a squeaky clean reputation. People are people and will make mistakes / do things that they shouldn't, but as long as they aren't actively hurting anybody / harassing people / etc. and they are talented and fit the role why wouldn't Disney try to get them on the project?
