I really think that most people, even those in tech, are blind to how easily the world can be manipulated as long as it's not a threat to corporate profits.

If your propaganda campaign lines the pockets of Facebook, Google, Twitter, etc, then they are open for business. Also, if the company refuses the business by banning propaganda accounts or creating special rules for who can advertise, then they have entered the political arena.

It's not very expensive to force a meme.
