The monetization however only works if money is to be made on users, this wasn’t a problem for years because of Google / Alphabet subsidizing YouTube, but in the end, a service should make money either directly or indirectly. And this is what the changes are about. This however is perceived as enshittification,

It's true, but it's still enshittification because they offered one quality of service and then downgraded it to another level entirely. Many companies have done this and I'd even say that it's planned enshittification. You start out by providing something financially unsustainable, such as (relatively) ad-free high-quality video streaming. You do it so well that you drive everyone else out of business. THEN you either raise prices or force more ads and tracking.
