Yeah, it's ridiculous. A typical libertarian screed you'd see from econtalk. Essentially the argument is it's free, and sacrificing your data and privacy isn't an actual cost. So where are these companies making money then?
If you value your privacy and data, it is a cost. At this point it's just nitpicking over value judgments. The kind that economists refuse to believe are important in society to try and have some artificial moral high ground. Similarly, when I go to work, I love it, so it's not actually sacrificing anything for money! ROFLcopter.
