Like imagine a label on a thing that says "Made without CNC machinery". So instead of finishing the thing on a CNC mill, they instead stuck it on a Bridgeport manual mill, and finished by hand. Or somebody finished the cast with a file.
Okay, and so? In the end, a hammer is a hammer. If it hammers well, what difference does it make how it got that precise shape? It's not like some inherent goodness is being imparted by a hand file.
Now I get some methods have flaws to them, and some form of associated harm. The problem I see with blaming specific tools is that it's simplifying the problem too much. Eg, if the problem is taking jobs, then picking up one particular tool to blame for that allows manufacturers to use a different tool and cause the same sort of issue. If the problem is say, pollution, then it's not at all a given that the replacement method will be ecologically friendly.
IMO the better thing to do is to target the underlying problem. If say, your issue is ecology, then you want to certify that the manufacture is as environmentally friendly as it can be, not that the thing isn't made from plastic, or there exists the chance that the non-plastic thing will even be worse for the environment.
