The same thing occurred to me as a possibility, but saying that "it seems they are doin this" is way stronger than what we can conclude from this article. Do you have any evidence beyond "hey, this could happen"?
No, there really isn't hard proof which is why I'm assuming ars didn't jump to that conclusion.
To me what points to it the most is why would somebody rip off those RetractionWatch articles in India. It seems that something other than trying to increase ad revenue is going on here.
