No, I agree with the definition. What I'm saying is that quality of streaming services is not degrading. The price is going up but that's not the same thing.
And I already said that you have many alternatives: there's multiple competing services (who's competing with YT?), you still can buy disks, you can watch TV, you can go to the cinema, damn, you can even read a book. No one is locked into one source of entertainment.
Yes, I totally agree with everything you said. YT is enshittifying not because it has ads but because their recommendation algo got really really bad in recent years.
Netflix algo didn't change. You still have 'continue watching' and 'my list' on the main page, they added 'top 10 in your country' which is nothing like pushing content they want to show you (assuming it's accurate but I haven't seen any indications it's not), the search still returns accurate results, the recommendations are still 100% related to what I'm watching. Netflix never pushed any 'click-bait' content at me the way YT does all the time.
If you have different experience with Netflix and you found some changes that make your experience worse than you're right, it's enshittyfying. I haven't seen anything like that and I haven't seen anyone complaining about anything other than the price.
