This kind of complex leglislation already exists in many areas of the law: revenue collection being the most obvious one. We could choose to treat "societal harm" the way we treat "tax collection".
I'm not saying there aren't infinite edge cases and second-order effects - but we tolerate those already for many things. I'm not pretending this is simple or even desirable - I'm merely stating it's possible if we want to do it.
My biggest fear is that (like the UK Online safety act) this acts to favour the huge corporations because they are the only ones that can afford a team of lawyers. Any legislation should aim to carve out exceptions to avoid indirectly helping monopolies.
Great example. These companies are already experts at circumventing taxes, what makes you think they can’t weasel their way around some arbitrary written law?
Just look at the malicious compliance that Apple and Google have around the App Store stuff, they’ll find a way to comply with the law and implement different addictive dark patterns.
I’m not saying that I disagree that these companies need to be regulated, I absolutely do. I just think it’s going to be a complicated process, and not “oh just ban everything that’s an algorithm”.
And I have absolutely 0 faith in companies like Meta willfully complying.
