I get it, really. “For the kids” is almost always bullshit. But Zuckerberg (and originally Sandberg) intentionally targeted kids and intentionally tweaked algorithms to hurt them (e.g. the entire profit motive for Instagram is giving teen girls depression). Forcing them to, for instance, stop the algorithms from targeting kids would be a positive step that wouldn’t present the harms you’re noting (or be as completely pointless), IMO.
