Platforms compete for your engagement. Government regulators don't (except through war or if you are mobile enough to have them compete for your immigration).

Platforms compete for your engagement. Government regulators don't (except through war or if you are mobile enough to have them compete for your immigration). Dominant platforms can leverage their network effect to abuse customers for a little while. But they face competition and disruption if they keep it up, since users are generally more mobile between platforms than between governments. Bring on the platforms-as-regulators! But, please also regulate the platforms so they don't externalize costs to the rest of society.
