"The advertisers wouldn't do it if there was no money in it......."
Distinguish between the advertising industry and the advertisers, those who have something they want you to buy.
The money is in it for the advertising industry for showing the ads. If they really wanted to do something for the advertisers' profits they'd follow the following line of reasoning:
1. This person is trying to block us.
2. This person therefore doesn't like being pestered by ads.
3. If we pester him he'll probably give our client a miss when he might have otherwise bought something.
4. Breaking through his ad-blocker will be bad for our client.
5. We won't try to do it.
The fact that they don't think that way (nor do the publishers) should tell the advertisers something and one day they might actually catch on and pull the rug out from underneath the whole thing.
The fact that this hasn't happened yet tells the rest of us two things: firstly that the advertisers still haven't grasped the fact that they're not special snowflakes to whom this logic doesn't apply and secondly that the advertising industry is using this to sell successfully.
And remember, the advertising industry doesn't sell to the rest of us, it sells to advertisers. How good a deal do they get?
