Tesla was four guys with the brand name and nothing else when Musk came along six months after founding. Given that Musk was the first large outside investor and invested in/joined the company four years before Roadster (which he heavily participated in designing) deliveries began, I don't think it's unreasonable to call him a founder even aside from such being legal fact.
