That's the part that might not be true, unfortunately. If each individual content producer sees more return on their own streaming service than they did sharing revenue from one of the independent services, then that's better for them, even if the total pie got smaller. If that wasn't the case, you'd think we'd see some of them shut their services down and go back to independent services once their income drops.
Sacrificing a wide audience to extract more from the most dedicated portion of the fanbase isn't an entirely new concept, and it financially makes sense short-term (until you start losing some of those dedicated fans over time and don't have the mindshare outside your bubble to attract new ones).
Once Netflix isn't the only one that doesn't share their monthly subscriber numbers anymore, we'll know that they're beginning to at least question why they own everything instead of license their content out
