YouTube premium delivers the content you select to consume to you without displaying ads in-platform. If you then use that ad-free platform to consume content that includes ads, that's on you.

That doesn't change the fact that you are still getting delivered ads so it is not ad-free.

Correct, if you choose to seek out content with ads, you will see ads. Would YouTube premium need to block you from viewing that content to meet your bar here?
