Once upon a time I TA'd for Alex, and this comment doesn't seem fair.

Nearly all undergrad projects at UC Berkeley are group projects
involving 3 or more students. MOSS proved quite effective at
identifying students who did not work well in programming teams,
students who instead seemed to be dabbling in espionage.

Opinions vary on what, if anything, to do about cheaters. For those
who want to find structural and surface similarities between large
sets of programs, MOSS is a useful tool.
