People are playing this cat-and-mouse game with YouTube specifically, where they’ll circumvent the desire to block them for not rendering ads. I think this is a bad thing for users to do. But I mostly think it should make the ad providers uncomfortable. Because they know that most people won’t play cat and mouse for their content. In any case other than YouTube, people would just move on.

They know it. We know they know it, because if they really didn’t want to send bits to ad-blockers, they’d copy the first step of the back-and-forth that Google did with YouTube, and those users would no longer be a problem.
