Netflix could easily say that you do get your cut by them being able to lower prices due to any income stream they manage to get from the data they collect. Realistically that's the only way it could work unless you're suggesting that Netflix should pay you for watching their service.
What I eat, my shoe size, where I've been, the drugs I take, where I work, my mortgage and tax payments, the movies I like.
Netflix should pay me for the honor of storing, mining, analysing, and reselling any and all information about me.
Ditto every one else peddling my data. Exploiting me (and you) for profit.
I want my cut.
