Entitlement? He is entitled to not download and view content that he doesn't want to.

No one is obligated to alter their own behavior in order to sustain someone else's business model. How publishers make money is their problem to solve, and if they're publishing content on the open web that's viewable with web browsers, then it's up to them to decide how to deal with the fact that some web browsers aren't going to download the ads.

They have plenty of alternative options: they can block all of the content unless ads are downloaded; they can put all of the content behind a paywall, etc. But most websites don't employ these methods, and do leave their content accessible to people who block ads.
