Via Thomas Sowell:
If, at a given time, three-quarters of the consumers prefer to buy the Acme brand of widgets to any other brand, then Acme Inc. will be said to ‘control’ three-quarters of the market, even though consumers control 100 percent of the market, since they can switch to another brand of widgets tomorrow if someone else comes up with a better widget, or stop buying widgets altogether if a new product comes along that makes widgets obsolete.
Should this apply to Google? Is Google a "utility"?
