Of course, they will not get paid for me visiting the website if I block the ads, but that was not my point. People have already bought stuff and with that paid for the ad budget. And that money will be spent somewhere. Maybe someone else will see the ad that I blocked, someone who would otherwise not have seen it because the ad budget would have been exhausted. Or maybe the prices for ads go up because there are less impressions to sell. Only if companies would lower their ad budgets in response to ad blocking would there be less money to distribute. If that would be the case, then my argument would fail.
