Here's the article. Basically he wants to steal computing power from privately owned vehicles when they are sitting idle and then pay those car owners nothing for the power consumption.
In other words he wants to hijack your Tesla's cpu and make YOU pay for the privilege
For someone who supposedly hates communism he seems to be really pushing hard for anyone who is not at least a millionaire owning no private property of their own lol
First mistake: you think you own that thing. Nope. Tesla thinks they still own it. You are just a user who paid big money for the privilege to be a beta tester.
In the perfect world it would be a great thing to do. Old enough people should remember SETI screensaver. But we are not living in a perfect world and I would never buy a car and participate in expenses just to make some rich clown even richer.
