I've been saying for years now - and I think it just gets more and more true over time - that we desperately need a Paramount Decree for streaming. For most of the last 70 years it's been the reason you don't have to go to a Disney theatre to see a Disney movie, basically.
A similar thing now would also make it much harder for streamers to hide the value of their shows and movies from the creatives who work on them, since they would have to buy the rights and production would be funded out in the open. This is much like how the Paramount decree basically ended studios "owning" actors and writers, even though that wasn't the main purpose.
Sadly the days of there being any teeth at all in antitrust laws are long gone though. But the 1948 us justice department would have had no patience for this shit.
