But it's not just software that goes into a computer. And by ignoring the other ramifications in question, he's ignored a large part of morality. It'd be like me saying I'm an overall better person because my house has zero carbon footprint, while paying illegal aliens $1 a day to build it.
All that aside, we can handle that. This has been RMS's thing for decades. It's his other annoying issues that make him a liability to us now that we have bigger eyes watching linux.
Blindly dismissing the benefits of free software just because some other aspect of computing hardware is also important is short-sighted and/or silly.
I don't dismiss that using 100% free software is a moral good. But I do dismiss the "better than me as a person" claim because he's more ethical in just one area. (Or maybe more, but he only addresses that ONE area.)
