If he is such a horrible useless person, then why don't the people who 'actually' built the Tesla cars and Space-X rockets step up and claim their rightful dues

If he is such a horrible useless person, then why don't the people who 'actually' built the Tesla cars and Space-X rockets step up and claim their rightful dues? Wouldn't they get tired of being led by some fake snake-oil salesman? Or, maybe the technology and innovation is being driven by Elon Musk working together with a bunch of other intelligent hard working people, and this is just a narrative being pushed out by a bunch of bitter gossip focused snake-oil journalists.
