The fact that you use their services despite claiming to oppose them probably tells more about how you really feel than your words do. You’re benefiting from their abusive business model the same whey they themselves are. Justifying the continued use of their services by not paying is just a cope to deal with the cognitive dissonance.
I prefer 1080p but if not available then 720p is perfectly fine as well. 4k is overkill and I don’t even have a monitor that could play it at native resolution. Where I do prefer “lower quality” though is framerate. I don’t like how 60fps looks so I force YouTube to play videos at 24fps.
