Private companies are the current gatekeepers to free speech, to propaganda, to censorship, to surveillance. They can not disregard human rights and principles of free society any more than a government can - just as they can not violate human rights. Just because its an oligarch and not a politician, the rules of a free and just society don't suddenly change. Private companies have some property. Their property rights do not supercede human rights. Then, another solution would be to dismantle the oligarchic model of economic management and provide the mass of people with the property rights of the platforms of their own free speech. But I suspect that our society isn't ready for anything that radical and must in the meantime merely hold private property accountable for its partnership with government to circumvent sovereignty restrictions.
