They're all really cartels, Google, Twitter, Facebook.
A small newspaper in the UK launched a campaign against the Google and Facebook duopoly because they are sucking up so much of the advertising dollars online:
"By 2020 it has been estimated that 71 per cent of the money spent on digital advertising in the UK will go to Google and Facebook,” the Press Gazette’s official petition reads."
they are already 1 cartel.. called the deep state.
