I also wouldn't be surprised if like we saw with Hulu at one point when coloration happens that there is some ownership stake involved - streaming service gets the content in return for some percentage of the company or something. That helps both. The person selling gets some of the profits and isn't in just a contract situation. The streaming service benefits since that content isn't part of just a contract so there is no danger of it leaving the company.
I always thought the original Hulu model made a lot of sense, joint ventures that bring content and shared ownership/profit. Then that model fell apart with NBC going their own streaming way and Fox selling out to Disney. Would not be surprised at all to see it come back full circle after the inevitable consolidation.
