So, while no one else is able to stop the authoritarian takeover, Big Tech will make a bold stand, sacrificing their cash and Most Favored Industry status for their altruistic principles.
If that doesn't sound absurd on its face, you've internalized some of your employer's propaganda. It's not just aimed at customers; it's aimed at you, and your coworkers. They let you and your friends have your little culture, beliefs, and morals. But when the dictator's call comes, you and your friends won't be the ones making the decision.
Your employer's contributions to the fascist project will be hidden from you to the greatest extent possible. At the point they can no longer be hidden, any serious dissenters will be fired. Keep in mind the economy will be tanked by then. Your friends will fall in line, or fall homeless in the street, which by that point will be a ticket to one of the concentration camps.
