Those stories about Adblockers selling browsing history and private data, is just a lame intent to make people stop using adblockers and make us digest all that advertising crap.... Watch an ad is our choice....
While advertisers would benefit if people are afraid to use adblockers, it doesn't necessarily mean that they did it themselves.
There was clearly a market for user browsing data (since WOT was able to find customers), so if WOT is shut down, more will pop up. And the apps that mine user data don't need to be adblockers, that's just the reason they give users to install the extension.
