Sorry if you disagree with my example, but to me they are the same and a good comparison.
Studio A produced content. Streamer A (same company) pays for content. Money is still being exchanged within the same company for said content.
The fact that said content (in the case of Netflix) never went or had limited theatrical release is irrelevant for the conversation of streaming paying for said content. In fact one could say that Netflix is more at risk here since they don't have a wide theatrical release, but that is a different conversation.
As brought up before the streamers, whether Disney or Netflix, has to pay a "fair" price for content even created within the same company as there are still payouts for creators tied to that content.
The piece that none of us really know is what Netflix pays out for a first run movie. However with the 5 year deal between Netflix and Sony, rumored between $1B-3B, one has to assume given the number of movies that it ends up costing Netflix at least $100M for some of those movies, sometimes more sometimes less.
So that brings us back to TLM, is $100M D+ is paying a fair price, when looking at the Netflix/Sony deal one could say yes. Again doesn't matter whether that is being paid by internal streamer or external streamer, its still being paid.
