And for thoroughness, allow me to add "even if they have no intention or 
desire to profit monetarily." I can't explain exactly why this is the 
case, but it seems to be true in the overwhelming majority of cases. 
Academic projects with non-commercial clauses languish in obscurity 
while academic Open Source projects thrive. The contributors to the Open 
Source projects value knowledge and learning just as much as the lonely 
developers of the non-commercial-only projects, but for whatever reason, 
they don't contribute to those non-commercial-only projects.
