A lawsuit settlement agreed to by Eberhard and Tesla in September 2009 allows all five – Eberhard, Tarpenning, Wright, Musk, and Straubel – to call themselves co-founders.

Which I agree is sort of showing the trick and explaining how it's done all at once. But I wanted to give the headline writer a little bit of the benefit of the doubt that they actually looked it up somewhere other than on the Tesla website.
