It's not everyday that the clubby world of venture capital engages in open warfare among investors. Even less so when the feud involves a 250-word missive laced with fiery language, metaphors and Latin edicts worthy of a Middle-earth battlefield speech, or a roof-shaking sermon ... or maybe just an indie-rock song. But that's exactly what happened early Wednesday when Uber investor Shervin Pishevar sent out a remarkable statement blasting a faction of Uber's board of directors. It's a heavy piece of writing, extrapolating on eight months of drama at the embattled ride sharing company.
