Many of the biggest tech platforms, from Amazon to Facebook, follow a similar pattern of transformation, according to a recent essay from the author and internet activist Cory Doctorow. First, he says, these platforms court users with artificially low prices on products or an exciting way to connect with friends. Then, they hook sellers, like advertisers or third-party retailers, with promises of reaching a captive audience. Finally, Doctorow says, as companies try to maximize their profits, they end up ruining the experience on their platforms through a process he describes with a four-letter word we can’t broadcast or publish.
