Right. No one is going to do that, because they make money off of ads.
This is why every other implementation of ad-blocking does not require the website owner to make changes (because they wouldn't, that's why there are resource hogging ads everywhere, because they put them there).
It's not their choice, that's the point. They can deny access to the site or app if they detect ad blockers enabled, I'm fine with that. I just think they'll lose their audience if they do. But what apple has done here is enabled the absolute minimum amount of ad blocking because they are at competitive risk if they can't at least check the box.
