I dont think they ignore fans concerns. I think that there will never be pleasing everyone, people have extremely strong feelings about how these films should be. When they dont turn out how they want, or how they expected, fans turn angry.
TBH, I think the problem with Solo is that they TRIED to please the fans, and in the process they canned two very good directors for not toeing the company line and doing their own thing, and in the end they went safe which has seemingly backfired.
