They didn't do anything wrong. They got richer because the shutdown forced everyone inside their homes doing nothing but talking on social media all day long while ordering everything on line delivered to their door.

It's their money now and it should be left up to them to decide what to do with it. I'm sure a lot of that money will be donated to charity.
