The tech giants' business models strongly incentivize maximizing the time a user spends within their app. To do that, their algorithms try to find the most engaging content to show you.

The most engaging political content is often hyper-partisan, outrage-driven, and unconcerned with truth. These algorithms encourage bad faith participation by all players: media outlets, individuals, and politicians. Political ideas are often shared not out of deep seated belief, but in hopes of distribution.

Democracy seems predicated on the idea that most participants will engage in good faith. Whether we like it or not, our civic discourse has moved over to platforms that seem to incentivize bad faith participation. I think that's cause for alarm.
