I am not a lawyer, and even the annotated QPL
http://trolltech.com/products/qt/licenses/licensing/qpl-annotated
starts with a disclaimer that their annotations have no legal value,
but the idea of the QPL is that closed source code must be made
public on request

5  c. If the items are not available to the general public, and the initial 
developer of the Software requests a copy of the items, then you must supply 
one.

This is to avoid problems with companies that try to hide the source. If we get to know about it we want to be able to get hold of the code even if we are not users. In 
this way, if somebody tries to cheat and we get to know we can release the code to the public.
