It's not just the extraction of data, it's also the optimisation methods:

- Make it a legal requirement to display on the website what optimisation techniques are used and what metrics are optimised.

- Create recommendation systems/search engines/web browsers as a public good, with utilities that are more humane and as such reduce the effects of addictive and harmful software in the medium term.

- Legislate on psychoactive software with the same fiduciary responsibility and oversight as applied to doctors and surgeons.
