There’s a difference between free speech and access to global loudspeaker. You don’t have freedom to get maximum engagement.

Twitter and Facebook are dangerous because they allow anything that gets them money. Political campaigns and foreign influence campaigns wield armies of bots to spew bullshit.

People of more libertarian bent tend to focus on some idealized vision of free speech. When those platforms enable fascists to overthrow democratic governments, you’ve won the battle and lost the war.
