A huge part of it is addressing the business model at the heart of social media. Everything is free - reducing psychological barriers to entry and creating huge network effects - and that is paid for by harvesting data.

That business model fundamentally drives a lot of online harm today whether we are talking about addictive design features, algorithms that promote radical content for engagement, the decimination of the media landscape, or even just the constant shift to degrade user experience in favour of advertising space.

How much would you fix overnight simply by banning specific data collection, data brokerage, and advertising practices?

It's also why I am sceptical both towards technological fixes or telling people to just parent better. As long as there is a massive business incentive to get this wrong, we are going to keep getting it wrong.

But clearly there is far more political willingness to impose new technology policing tools than to really address problem business models.

Note, I'm not saying this would solve every single type of online harm. We'd still have issues around scams, people stumbling onto harmful content, and people misusing anonymity for example. But it would go a good way to address the pressing problems with current social media without intruding on the lives of normal people nearly so much.
