because they bring life to the conversation
What life exactly? Maybe on Ars site where they have loads of comments but on another site they are just parasites. If you don't want to see the ads don;t look at the content.
If your business model is make or break because a percentage might not see your CPM ads you might as well close your doors.
Why would that be? If you are a news site then most of your revenue will be CPM and some CPC, maybe a little CPA. That is the revenue model.
If a site has mostly CPM advertising revenue then say 20% more people start using blockers and are not seeing the ads then obviously it will badly impact your profit. You migth only have a 20% margin.
They are right to point it out and indeed adblockers make it worse for everyone else as it puts pressure on publishers to try more intrusive or 'innovative' advertising in order to maintain revenue.
I bet they lots of them will be first in line to complain when all the sites start going behind pay walls, which is the only alternative to advertising.
