I’m sure they did and that they did so sincerely, as they did with Downey, and I truly wish all the best of luck. Seeing others achieve their potential is a source of great joy, and I think ad is potentially a “captures the imagination” kind of talent. And if ad’s issues are not medical, then shame on me and apologies to him and his family.
But in virtually any personnel decision (including ones in my own business) involving high risk/reward people, there is often a very difficult-to-resist temptation to think “we can change him/her for the better in our environment”. Unfortunately in my experience it’s often just wrong. But who knows, if there is a medical issue here and it’s being recognized and dealt with as such, maybe that makes it easier to deal with effectively. Hopefully so. But if it’s medical and dealt with thru “mentoring” which some seem to have suggested as the magic bullet, well, you may need a little good luck as well. Personally I don’t think one can mentor ones way thru mental health issues any more than one can mentor ones way thru a broken leg.
