You're straining to take offense, and so imagining slights against these people that weren't present or intended.
Really, many of the people doing online piecework, like Cha-Cha answers or MTurk tasks, aren't even looking for a real clock-in job. They're just engaged in a diversion, and happy to be making a little on the side. If they weren't doing the piecework, they would be Facebooking, IM'ing, TV-watching, gaming -- something else they can do in dribs and drabs at home. In fact, they may be doing all those things simultaneously!
If your preferred crackdown was enacted -- abolishing their current arrangement -- many wouldn't even look for one of your "fair" regulated minimum-wage jobs, clocking in at some office or fast-food-joint.
I respect them to make their own decisions. You "color these people" as if they were helpless victims "who let themselves be taken advantage of" and "aren't using the same judgement and resources to make their decisions as those who know better". That's more denigratory to voluntary at-home pieceworkers than anything I've said.
