The same applies to the GPL, as far as I remember.

You have to provide the source code to those people who get the binary.

So for in-house use or willing customers, nobody else gets the source.
 
Whenever a community wants to have something "for internal use" only, 
nobody can force them to give GPL'ed products to the outer world, thus 
making it "practically" closed source.

There's only one advantage to commercial licenses: Every user also gets 
the right to access the source, and so is independent of the vendor 
whenever the vendor decides not to support the product any more. (But 
even this is limited to three years according to 3) b) in GPL 2)

Note: This should _not_ be an argument to make you use the GPL, simply 
a description of a fact that lots of Open Source fanatics don't know 
(or ignore).
