I said "stoke and profit off of", not "exploit" - devs have free choice and simply need to get informed about where their incentives are (mis)aligned. I also never said these platforms don't do anything to create value. The issue is that they can prosper even if the typical dev is throwing his time into the meat grinder, and devs should realize this rather than assuming that because a market is large it is viable for the average (or even above average) participant.
