I frequently see people on HN link to these sorts of biased content farms sites when groping around in the dark of the internet in a frequently very successful bid to back up falsehood in heated political debate. They are doing that for free and they basically never get called out. In a commercial setting where you have paid people who's job it is to do that from 9-5 and where things are generally far less controversial and therefore far less subject to challenge I can only assume the proportion is higher.
