The author claims it's not just that one evangelizes it, but that they become hostile when someone claims to not have the same experience in response. I don't recall Either Willison or Antirez scaring people by saying they will be left behind or that they are just afraid of becoming irrelevant. Instead they just talk about their positive experiences using it. Willison and Antirez seem to be fine to live and let live (maybe Antirez a bit less, but they're still not mean about it).
