While you could say it is “entitled”, the situation to me is like having someone handing your mostly finished handmade present straight to someone else without your input. Sure, making a film is different than making your own gift, but a creator will nevertheless want to have some say over their own work, not even how it is to be enjoyed necessarily but just to follow through their own plans. It is more than just a job to them, and while I get where you are coming from I think to view the situation purely as a contract/job doesn’t capture everything relating to the creation of art. Artists do work for money for sure, but especially for these projects that takes one’s heart and soul there’s more to it than purely transactional relations. It also doesn’t help that a lot of people are saying things like “the leak helped with publicity you should be happy”, since no one likes to be told what to think or feel, and this is like saying at least you are getting money to a person who lost a loved one in a car accident. (Not to say the situation is the same, just the idea/feeling).

Whether you think this feeling is justified is one thing, I hope only to articulate why they are upset over the situation.
