Aggregators, by virtue of owning demand, gain power over suppliers which become modularized and commoditized.
Google is winning with AMP and blocking ads in Chrome: both seem bad, but aren’t they actually good for consumers? That is the paradox of aggregation.
Publishers are trying to threaten Google again, apparently unaware that because of the Internet they have no power: that flows to the platforms that control discovery.
Ride-sharing is a winner-take-all market that depends on controlling demand more than it does supply.
