Those "bunch of extra features" are paid features for the service though. For which you're not paying.

And which they are unable to use even if they were to pay for them, as they depend on Google Play Services.

This is actually the situation I'm in. Google Play Services are disabled on my device so I cannot use any YouTube premium features anyways.

If there was a way to pay for YouTube premium and make the money go to the creators I watch while using a FOSS client like NewPipe, I'd be willing to pay several more times the current price of YouTube premium for that.
