This. It's the new trend in streaming: Get better ROI for funding new content instead of paying residuals on your back catalog. The market is heading in a direction where subscribers won't just stick around forever if you're not constantly feeding them something new. So it makes more sense to put the money there instead.
"Max" has already dropped a lot of original content for this exact reason. And you can expect to continue seeing this trend across the streaming industry.
Remember the ongoing writers' strike? The pittance that they get paid in residuals from streaming is one of their main complaints. So you can expect the practice to accelerate after the strike is over.
The content will be shopped around to other platforms. You can probably expect some of it to end up on freemium/advertisement-based streaming services. The rest will just go into the proverbial vault.
