Eh, their motivations were certainly understandable and their grievances valid, but their way of dealing with those grievances very flawed in my view. Producing more stuff with less labor, and allowing production to be done with less requisite training first, aren't bad things in of themselves, they increase the potential wealth available to society at large in increasing the total output the labor pool can create (though this may not seem so apparent if that technology and associated wealth is hoarded by a few, as has and continues to be the case).
The issue was less the machines themselves and more that the wealth generated by them was not distributed equitably, trying to solve this by being rid of the automation tech is throwing the baby out with the bathwater, though it is understandable how that stuff would become the target of people's frustrations.
