Currently only Netflix is profitable, e.g. Disney lost more than a billion on Disney+. Not sure how they can keep this up if people keep moving to piracy.
Hollywood accounting makes it very hard to trust tales of "losses".
The money has just been siphoned away to a tax haven somewhere through overpaying for e.g. renting a property or licensing some IP. The money wasn't really "lost", it was just not taxed.
I'll believe the poor rich people who are struggling to buy their third yacht when they open up their accounts books and show where all the money comes from and where it goes to. As long as they keep it secret, I'll assume it's because they don't like paying taxes.
