The main thesis seems to be that framing the problem as health issue (as the so called Tech Humanists try to do) is: - hiding the political issues related to the power the tech companies have on our lives - giving them even more power - because they are the experts here and in health we defer a lot of our judgement to the doctors - is based on a mythical 'human nature as separate from our technology' idea
What to do with it: use anti monopoly laws, tax, introduce rules about the usage of private data and build public/coop infrastructure.
I am not so sure about public/coop infrastructure part - I don't think government is automatically better than a company - but maybe it should be tried. But the most difficult part will be the 'rules about usage of private data', that goes much deeper than just 'protecting privacy' and I am not sure how it can work - you cannot stop an individual from thinking about you and using all his memories in his thinking, sure a person is not a perfect analogy to organization.
By the way, the Facebook 'time well spent' project priorities our private communications over public ones - it is really about hooking us even deeper into the machine.
