How likely would advertisers be to refuse to allow the Adblock ads? I don't really have a problem with ads on websites, experienced users can easily block them, but I see no problem with providing ads for a free service. Many organizations only have three methods to generate revenue, either show advertisements, have paid memberships, or take donations. Google shows advertisements, Apple has paid memberships, Wikipedi…
"Plus if Adblock is actually successful and the online advertising industry collapses, then they will be putting themselves out of business." Even worse. Some of these companies (not adblock) are asking protection money from big advertisers to be whitelisted. Mafia style.
Maybe this is well-known, but my google-fu only turned up this news about Adblock Plus. Are you sure Adblock does it as well?
When I used adblock as the search criteria, I got a bunch of hits on it. But when I did adblock -plus, I got nothing primary that could pin this activity to AdBlock.
