I agree, and I think I might have even used this argument before. ;)

It does scale solely for GNU Parallel though for now, and very few other people have taken the same tack as GNU Parallel’s citation notice. Despite the potential for a slippery slope, it doesn’t seem to be happening. I’d speculate that if it did start to happen, then GNU would change their stance on what’s allowed by the license, perhaps.
