This is, indeed, the whole truth and nothing but the truth. My own anecdote: through happenstance I'm co-author on a paper, a large number of my friends are PIs/PhDs etc and one of them needed help after the software written for them by the CS student they'd been assigned didn't work (he got a masters for it, I can't believe anyone in the CS department looked at his work). I asked about publishing my code after the paper was published and no one seemed bothered.

I've also seen my friends on the mill of, shall we call it paper chasing? That seems most apt. It reminded me of borrowing someone's homework and making minor changes to get it past teacher - except the homework was the same paper being constantly rejigged for submission to a new journal. Not much truly new work seemed to be going on.
