I think there are a fair number of JavaScript devs who really don't appreciate being told that they are on the same ethical plane as, e.g. cigarette designers, which is pretty understandable even if one does think that JavaScript is basically cancer (a position I would not take myself: I think it's more akin to sugar: good or at least neutral in very small amounts). No-one wants to be told that the way he earns a living is fundamentally wrong. Or, in the words of Upton Sinclair, 'It is difficult to get a man to understand something, when his salary depends on his not understanding it.'
