Yeah, sorry, I realized after I commented.

Imagine there's a business that can't really enforce whether you walk out without providing compensation. You realize you have the home court advantage on enforcement and guess what, you don't want to pay. It's your browser/wallet and that's your prerogative. But what does that mean about how tempting their goods are? Do we have prerogative to these goods?

Should we live in a world where we only permit business models that require customers pay directly or don't enter at all?

You know, I do not actually know that a website had ads before clicking on a link to it; I would be happy to only visit websites without ads.

It’s scummy to shove ads in my face without at least warning me and giving me a chance to leave, I think.

Fair point. There should be a header to reveal whether the payload has ads. Then you can refuse right there.

Of course there is a means to enforce payment, paywalls. Ads are a particular model for monetization, it does not mean it is the only one. How about when you want to see a movie, nobody will let you in unless you have bought a ticket. Now of course theaters know that you have paid, but they still say, hey, here are 30 minutes of ads to go with your movie, but then it is then fair for us to show up late.
