Sure, but its also run and operated by the rights holders, which they never even needed to do.
replyIt's more "streaming/delivery operators which also have some of their own licensed content":
reply- Disney -> Disney+/Hulu
- Universal/NBC -> Peacock
- Warner Bros. -> Max
- Lionsgate -> Lionsgate+
- Sony Pictures -> The Sony services relevant to the article (note: the Sony services sell more than just Sony Pictures content)
They never needed to, but it actually makes them more money because a revenue share model through Movies Anywhere makes sense. StudioCanal does not sell streaming/delivery services directly to consumers, a revenue share model between streaming providers would not make them more money, and Sony would have no influence on StudioCanal doing so anyways.
