The author claims, "Internet surveillance, the algorithmic polarization of social media, predatory app stores, and extractive business models have eroded the freedoms the personal computer once promised, effectively ending the PC era for most tech consumers."

I'm not required to use social media and extractive business models. Intenet surveillance is lamentable but I don't see why he thinks app stores are predatory. The PC is still mostly a force for freedom. The privacy losses are more than offset by the gains of communicating with everyone on the planet.
