There is nothing in the open source licensees that prevents charging money, in fact, non-commercial clauses are seen as incompatible with the Debian Free Software Guidelines.

And there is a lot of companies out there that make their money based on open source software, red hat is maybe the biggest and most well known.

I meant in the sense that someone else can redistribute the source for free, not that the company has to do it.

> The license shall not restrict any party from selling or giving away the software as a component of an aggregate software distribution containing programs from several different sources. The license shall not require a royalty or other fee for such sale.
