It’s because they are all fascists. “Conservative” in America is just a synonym. Fascism has always historically been a boon to corporations due to their integration into the corrupt machine.

Corporations could not care less if someone is “conservative,” what they care about is money, power, and control. And fascism seems to be a good way to get that done, while also having the added benefit (in their minds) of causing millions of humans to suffer.

Win/win.
