I'm not sure why that follows- if anything, in my experience pandering propaganda tends to increase profits - just look at Breitbart on the right and Huffington post on the left. It drives clicks just as well and seems to be cheaper to produce than real investigative journalism.
As TFA mentions, the authors have been cut off from the ad revenue. So it may be producing a lot, but only the hosting company is getting it, if the article is to be believed.
