This article doesn't help answer it. It's just a journalist trying to justify a more emotionally powerful and eye-catching form of journalism in a world where a huge number of people are already addicted to doomscrolling. If anything, we need mutual disarmament in the area of giving people an endless stream of depressing and enraging news in ever more optimized ways. I would treat this piece similarly to an oil industry worker explaining the benefits of using more fossil fuels, or an alcohol industry executive expounding on the positives of drinking.
