Making people less addicted to social media, or creating other versions of social media that are less harmful, might be the "harm reduction" discussion/tradeoff of our modern times, but they're very different goals and ambitions. Sure, I agree, people shouldn't spend hours mindlessly scrolling through TikTok/Instagram/Whatever, but most likely they will, regardless of what we do. So, why not come up with some alternative that kind of gives them that experience, but not as addicting and with maybe more user choice, like Bluesky letting people chose their own recommendation algos they like?
