The quality of their code looks pretty terrible too. For starters, just look at their genMakefiles script (something of a WTF itself - y u no configure?):
I wonder if the classic excuse for not open sourcing software applies here - that the developer is ashamed of their source, that they think it is messy and no one will like it, applies here?
Either way, one shouldn't really overtly negatively criticize - it probably wouldn't encourage such a developer if they do have that thought.
That's a pretty weak example to argue that their code quality is poor.
They didn't bother to set up a for loop, for only 8 iterations. Their version is still perfectly legible, and you don't have to worry as much about shell argument expansion, which nobody really understands fully.
