It doesn't need to.  Without an explicit contract term to the contrary, 
the copyright owner can give many different licences for the same code.

I think you have fundamental misunderstandings of what a "licence" is, 
possibly because the proprietary software industry actually uses the 
term to refer to restrictive contracts, not simple licences.

It has wording which permits charging for supply and support, and which 
doesn't permit discrimination against classes of user.

That means ŧhaere are business models that can be based on the supply of 
GPLed software (e.g Red Hat) and ŧhat businesses may use GPLed software.
