TFA mentions 4 recommendations that social media platforms can implement to prevent the abuse of their users. These aren't even political, but pertain to the practice of doxxing in general.
And like a sibling comment mentioned, companies should operate separately from governments. When that separation is blurred the checks and balances that are supposed to be in place in order to keep companies from abusing people, and from being an extension for governments to do the same, are just gone. At that point the country becomes a corporatocracy, serving the interests of companies rather than citizens.
The US has arguably functioned like this for decades, but when there are literal businessmen in power this is more evident than ever before. It's how you get scenarios of presidents manipulating the economy for their and their cronies' benefit. The next step is complete authoritarianism where companies are government puppets, where the spread of and access to information is tightly controlled and sprinkled with their own propaganda in order to keep megalomaniacs in power, and where any dissidence is squashed before it has the chance to spread. This is how you get China, Russia, and any government that aspires to that formula.
It's crazy that this needs explanation, or that it's a controversial line of thought.
