I think most people are angry with YouTube premium because it's a service that doesn't give you anything. It's a service where they stop annoying you. But it doesn't unlock anything new that you didn't have before, doesn't give you access to content or data you don't have access to, it doesn't improve the service. It just removes the annoyances they put there deliberately. So people are a little angry about it
It's a protection racket, for your attention and time.
