For Tesla it’s definitely a rebuke of his fascist ways. Germany’s boycott alone resulted in 76% drop in sales. The rest of the market is sending the mad king a message that his erratic policies will destroy the economy

I'm sure the tech giants do care. Their companies lost a lot of value. On the individual level though this could be market manipulation: individual regime members will have made sure & bought options so they will gain if the market drops.

Still: Hitler needed strong companies to help him come to real power, and stay in power.
