A good quote:<p>"Yet there are also important parallels. The monopolies of old and of today were built on proprietary technology and physical networks that drove down costs while locking in customers, erecting formidable barriers to entry. Just as Standard Oil and AT&T were once critical to the nation’s economic infrastructure, today’s tech giants are gatekeepers to the internet economy. If they’re imposing a cost, it may not be what customers pay but the products they never see."
