I mean that's the definition of the term "luddite" in our current understand of English. The only thing that could be labeled as propaganda is the application of the term to that movement
Still, it's important to know the story for two reasons. One, to realize that the "luddites" according to current meaning of the word never existed. Second, to realize that the people historically called "luddites" were fighting for the same reason communist revolutions happened, for the same reason you have a good chunk of world's population hating the elites (and arguably for the same reason many prior historical revolutions happened) - and it has nothing to do with technology. It's all about economic insecurity, about being poor, suddenly becoming poor, or being afraid of suddenly becoming poor, all while seeing fruits of your labor accumulate in your economic superiors' laps, and then trickle upwards towards the even more wealthy.
