Patrick Stewart was also deeply involved in the creative decisions on Picard seasons 1 and 2. He got to the point where he just wanted to do what he wanted to do, and since he is Jean-Luc Picard, what he wants is ipso facto the right choice:

“What I’d like to see at the end of the show,” I told them, “is a content Jean-Luc. I want to see Picard perfectly at ease with his situation. Not anxious, not in a frenzy, not depressed. And I think this means that there is a wife in the picture.” You see, the line between Jean-Luc and me has grown ever more blurred. If I have found true love, shouldn’t he?

Sometimes you do not want your actor actually in charge of their iconic character, and genuine embrace of it can manage to make it worse if they're not writers. I will do my occasional hornet's-nest kicking and say that Mark Hamill's take on Luke Skywalker after filming The Last Jedi was similarly myopic, but in a direction that more fans at least think they wanted, and since we'll never see his choices play out he still gets the benefit of the doubt.
