Oh, I have read it. Luddites were strongly motivated by loss of jobs. The article refers to this, and you can find plenty of examples of pamphlets and letters about this: http://faculty.humanities.uci.edu/bjbecker/SpinningWeb/week8d.html ("We know that it have been mentioned to our great men and Ministers in Parliament by them that have Factorys how many poor they employ, forgetting at the same time how many more they would employ were they to have it done by hand as they used to do.") You can characterise this as “technology should serve the common man, not the rich people” through a modern lens of class struggle, but the clear motivation at the time was simply loss of employment and the problems that brought. If they had a more complex understanding like I think you’re voicing, I think you would see their ire directed elsewhere rather than destroying the machines.
