Yes, I agree. It's made worse by older media not even handling credits properly; failing to credit certain types of workers or influencers. At least now it's not too hard to find and follow a money trail in modern media credits.

What I mean is the sort of situation we can see easily online now, where there's a definitive central creative lead, he means well, but he's surrounded by cretins trying to subvert him. It's sad, but a lot of creators can't seem to handle that kind of pressure; they cave in and compromise their own work.

It's not always the twitter-esque social pressure, sometimes it can be pressure from above. Even though the producer should be concerned only with profit, sometimes they meddle and the weird casting or bizarre event in a movie suddenly becomes "who really chose this? the director or some guy pulling his strings?". In the case that the creative talent is stripped of their control over the product, I don't expect to find easy evidence of it.
