Feudalism is where someone with a castle (a walled fortress) and armed men with steel weapons and horses offers to defend farmers in exchange for part of their crop each year. Often, those protected are forced to accept the bargain.

We have something like this now with Apple Computer. It's called Techno-feudalism. They offer their users some protection against invasions of their privacy in exchange for large amounts of money (high prices for Apple products and 30% of software purchases). Of course, like the feudalists of the Middle Ages, they offer no protection against themselves.

Elon Musk doesn't offer to defend anyone against anything. He isn't any kind of feudalist.
