To assume that Evil Corp Inc. does evil things? They should just turn the platform off because it seems is only thing that works as a bargaining chip with such powerful entities.
I suppose blocking/censoring Facebook/WhatsApp in Brazil would be one way of making sure their opposition wins.
Why exactly opposition? I mean what exactly are you supposed to do then? Let foreign actors meddle with your election? X is doing exactly the same thing as Meta around the world. I do not see any other solution than some kind of repression.
