I don't think people "like" it as much as hate elicits a response from your brain, like it or not.

If people had perfect self-control, they wouldn't do it. IMO it's somewhat irresponsible for the algorithm makers to profit from that - it's basically selling an unregulated, heavily optimized drug. They downrank scammy content for instance, which limits its reach - why not also downrank trolling? (obviously bc the former directly impacts profits, but not the latter, but still)

This comment has a remarkable lack of nuance in it. That isn't even remotely close to how how human motivation works. We do all kinds of things motivated by emotions that have nothing to do with "liking" it.

This is really a child like understanding of the world.
