But now also Google, Facebook, Instagram, Paypal, Patreon, MasterCard, etc. are deciding which one is right (i.e. the Left) and suppress what they define as wrong (i.e. conservatives and libertarians).
I have mixed feelings about private corporations operating according to their own values. Mixed because too many of these corporations are quasi-monopolies, thanks to government largesse and discrimination. But even large companies would hardly impose their values forcibly if they were not assured the government would not look the other way when it agreed with the action.
