Bas, Well said..... except...

you can distribute it for any fee, it doesn't have to be a low fee or  
anything,

this is what they say about it:

High or low fees, and the GNU GPL
Except for one special situation, the GNU General Public License (GNU  
GPL) has no requirements about how much you can charge for  
distributing a copy of free software. You can charge nothing, a penny,  
a dollar, or a billion dollars. It's up to you, and the marketplace,  
so don't complain to us if nobody wants to pay a billion dollars for a  
copy.
