Do you think digital media needs a state run mediator?
I think it's probably time.
We've become quite protective of the data that's collected by digital products for fear of a concentration of power.
But then we all see the internet as a great 'leveller', and we don't want to disturb that balance.
The likes of the FDA (or your local equivalent) work at a certain scale... Perhaps civilly agreed constraints can be applied to companies who have managed to cultivate a userbase of a certain size.
Like a 'tax' of a kind on the amount of 'trash' you're allowed to ignore, before the police physically ensure you and your users can't abuse state infrastructure for whatever your nefarious purpose is.
