1) seems like the pertinent disagreement, here. OK, fine, it's an opinion piece, and we shouldn't expect any sort of actual information from such a thing. Why, then, are we posting and upvoting such crap? Why is anybody defending it?
Agreed and agreed. The only reason I chimed in is because labeling an opinion piece as 'manipulation' seems pretty suspect. That is tantamount to saying "anyone who has an opinion I disagree with is manipulating me."
