Google and Facebook etc are acting like online government and run their censorship at will based on their own ideology, they need to be checked and held liable legally, the top management should go to jail for any wrongdoings. While we hate censorship from the government, the same should be applied to those de facto online big guns and those who actually are in control inside the companies.
