The sky is falling because of monopoly? What does that have to do with the juicer? People invested in bad ideas before this age of monopolies that the author is worried about, so I'm not buying the "nothing but scraps" argument. I'm not saying I disagree that tech companies should be brought up on anti trust charges, and in some cases broken up. But the author's arguments don't make any sense to me.
