Apple already doesn’t get any money out of Google. You can’t buy YouTube Live TV nor YouTube premium via in app subscriptions.
VOD rentals from Google Play Movies isn’t making money. I doubt anyone is making money on it. Everyone is charging the same thing. I assume that’s because there is no room to reduce prices.
Apple, Amazon, and Google care so little about revenue from digital movies that if you buy a movie from one service and link your account to Movies Anywhere, all of the other services just count it as purchased on their services. It’s a feature not a product that couldn’t be above break even.
If you search for a movie on Apple and it is available free on another service you subscribe to, Apple will just tell you.
The only play for Google here is advertising and collecting user data.
There is no realistic alternative where Google is any more than a bit player when you have Netflix, Amazon Prime, Disney, and all of the other players with real content. Google already gave up on originals on YouTube.
