No Public = No government = No internet or social media giants.
Without government protection, you couldn't even have private property. You need courts, law enforcement,..etc, and plenty of publicly funded, built, and maintained infrastructure.
The internet began as ARPANET, a government computer network. Much of the technology that these companies rely on was researched and developed with plenty of government support, sometimes exclusively funded by public funds in government institutions. Many of these companies rely on government permits for access to public infrastructure and land, not to speak of all of the contracts, loans, grants, and subsidies that the private sector receives from the American public through its government. If it wasn't for government protected patents, Amazon and Google wouldn't have such a large market share or monopoly.
To build broadband networks, internet service providers (ISPs) must install infrastructure on public and private land, and to do that, they must obtain permits and easements. Permits provide access to the public rights of way, such as streets, sidewalks or highways, and allow ISPs to place infrastructure within and to access the right of way for purposes of construction or maintenance. All of the aformentioned activities are in cooperation with the community through its government authorities.
The bottom line is that the community, the people decide, how commerce is conducted, what the rights are of these social media giants and monopolies, not you or me as individuals. It's the community that decides what they have the right to do and what they can't do.
Ukraine didn't have freedom of the press for those who expressed any pro-Russian sentiments before the war, and now of course even less. Ukraine is just as authoratarian as Russia so you have no moral highground upon which to stand and point your crooked, feculent finger at Russia. There's no justification for fighting WW3 with Russia over Ukrainian sovereignty. That's truly loony tunes.
