that's the way it works! thinking about a problem in your institute all
the day while you are getting paid from public money, and then typing it
into your computer at home. that's theft. how much spare time do you
have, anyway? is that enough to work on such a large project? i doubt ..
of course, everybody can decide about his own software, but this does
not seem to be the case here.
possibly, the head of your university would have chosen a more
reasonable license than the gpl.
