Software engineers idolize Tesla because they see themselves as the Tesla (a selfless devotee of the abstract idea of technology) against evil Edisons (businessmen who only care about money and steal other people's ideas). They've basically projected the Jobs/Woz divide back onto two historical figures who, in reality, barely interacted.

The funniest part is that The Oatmeal comic didn't invent this concept, but drew on pre-Internet narratives put forward by The Tesla Society, who were mailing busts of Tesla to universities around the country since the 70s at least. And that organization is explicitly nationalistic and religious, tied to other Serbian-American heritage organizations, and doing events with the Orthodox church.
