You like it now, just wait though. In another year "YouTube Premium" will probably split further into basic and premium plus tiers. Basic will cost exactly the same except you now have to watch "limited" ads again, while Premium Plus will cost twice as much and be basically the same thing you're paying for now plus some new bullshit feature no one cares about.
This is what YouTube has become. It's what all the corporate services that like to make you think they care about you do. As long as we all keep shelling out more money for less services they will all just keep pumping us for every dollar they can possibly get.
It's an unethical strategy called a "loss leader" where these companies offer a service they actually lose money on for a limited time until they get you to the point that you take it for granted. Then they make that same price point terrible and jack up the price for the good service you've come to expect.
