Provide a link to Stallman using that term then please? Otherwise, I'm calling nonsense. I'd be 95+% sure you're making that up, or confused in this case.
I didn't mean to be nasty - I was, apparently, misunderstanding OP's original message. In my defense, the causal link between these three things:
1. Person A in their blog appears to be using a weird portmanteau, "computard"
2. "Some famous people like Stallman do this" (referring to portmanteaus, and making up words, in general, and not the specific portmanteau person A used)
3. "People" maybe don't perceive that positively (making up portmanteaus..?)
is more than a bit hard to follow.
Anyway, I thought an obviously false claim was being made, but if it's just a few loose amalgamations and people brandishing their opinions about, well that's fine, it is the internet, after all.
