I’m sorry but “evangelist” to me conjures an image of a techbro on a street corner with a makeshift shelf of Google Cloud brochures advertising free documentation study hours.
There’s Jehowa Witnesses doing the same schtick one block over and they’re absolutely furious he took their favourite spot.
Did no one tell them that “evangelist” is not exactly a positive term? Do they call their sales people “crusaders”, too?
