I'm the opposite. I'm happy to pay for premium when logged in, but I don't like the echo chamber being built so I prefer to watch logged out, in which case I'd get ads without the adblocks
(As a point of pride, lest I be intrepteted as a corporate simp, I should add that this is an account I use entirely for leisure browsing and that's disconnected from the rest of my identity. I created it with Apple HideMyEmail and avoided supplying any phone number by setting up 2fa with a virtual WebAuthn device so I could setup a TOTP code, then generated that and saved it to my psssord manager.)
You don't have to run WebAuth on a VPS, you can use it on your PC/Mac or even on your phone..!
Clear cookies and site data for YT and login again.
I like being logged in because I like to track what I've watched. So it's annoying to lose that when logging out. It'd be nice to have an extension that provides watch history independently of YouTube, so that I don't need to login.
