I think addiction is a key aspect. Like with gambling there is of course that aspect of responsibility, but regulation to minimize harm is also important.

All the major social media apps being designed to exploit that dopamine response is kind of like junk foods being the most common due to being subsidized; of course people just shouldn’t eat junk food, but we should make healthy options the most prevalent and common instead.

Of course that would require a government that would actually force corporations to implement harm reductive measures, instead of one bought by and working for corporations…

FOSS alternatives like Lemmy, Pixelfed, and Loops should be much healthier due to no algorithm working to maximize engagement. I also think social isolation is a big part of the addiction aspect, at least in America
