I can agree with this one. Of course, as you said, there are other metrics we must take into account. Only using the LOC metric is not enough to make any decision.
I've had similar experiences to the ones you talked about where developers underdeliver (or at least it seams like it, from the LOC), and it can be hard for the team, demotivating and infuriating in some cases. But in some cases we were looking at the incorrect metric, and or missed a lot of context on why they delivered so little. In the end I think we should take LOC into account, but not only look at that, but also look at other metrics.

Free riders surfing on other peoples' work is the worst thing a company can experience. It demotivates everybody ... :/
