> To be clear, I'm not opposed to the practise, as long as that's clear up front. YouTube advertises Premium as an ad free experience, and in reality it's full of ads.

I think it's clear. I don't want YouTube going in and editing movies and creator videos removing any form of advertising. Maybe you want them deleting that content. But the average person realizes what Premium means by no ads. Being obtuse or willfully ignorant isn't reasonable.
