Why do you think Apple would not do that?

Will Apple let me see website that "replicate iOS's built-in functionality" or fail review, or don't pay a $100/yr listing fee?

The company has the option to stop providing their service to users who use adblock. And they have decided not to do that. If they don't have any issue I don't see why I should have any issue using adblock either.

Y'all are jumping through some serious mental hoops. Nobody on HN can claim to be naive enough not to understand the ad model of financing content, so ad blocking IS essentially theft. Avoid the content if you find the means of paying for it objectionable; vote with your wallet.
