The luddites or at least some of them threatened employers, factories and/or machinery with physical aggression. They lived in the locations where these industries for a long time remained tho automation certainly made the industry more mobile. Like unions they used collective bargaining power in part derived from their geographic location and presence among each other.

A Guatemalan or Indian can write code for my boss today...instead of me. Software engineers despite the cliff in employment and the like are still rather well paid and there's plenty of room to undercut and for people to disregard principles. If this is perceived to be an issue to them at all. If you talk to many irl... Well it is not in the slightest.
