As it should, because there's a really obvious "slippery slope" argument right there.
But… it can kill people.
There is a certain fraction of the population who, for whatever reason, can be manipulated, to the point of becoming killers or of causing injury to themselves. Social media… actually, worse than that, all A/B testing everywhere, can stumble upon this even when it isn't trying to (I would like to believe that OpenAI's experience with 4o-induced psychosis was unintentional).
When we know which tools can be used for manipulation, it's bad to keep allowing it to run unchecked. Unchecked, they are the tool of propagandists.
But… I see that slippery slope, I know that any government which successfully argues itself the power to regulate this, even for good, is one bad election away from a dictatorship that will abuse the same reasoning and powers to evil ends.
There's also a very good TED talk on this topic from 8 years ago: https://www.youtube.com/watch?v=iFTWM7HV2UI
Why would you not be willing to include "scrolling" as another form of addiction? Just because it's labeled the same way you yourself are demonstrating that we handle that in different ways.
Social Media is being treated as "sugar" in this instance instead of as "cocaine".
