I haven't been a subscriber for a long time, but GOOD ON THEM!
I don't see why Apple deserves any percent of a Netflix subscription, or any streaming platform's subscription. I make a point to sign-up on the web for all my streaming apps.
It would make more sense to me, maybe, if they paid Apple a one-time customer finders-fee on someone who signs up for a subscription on an iPhone, but not a monthly commission. Apple isn't doing anything monthly to retain the customers.
If I were Netflix, I would completely remove the app and just go webapp for the iPhone.
No need to argue. That's just my opinion. Not trying to change yours!
