I hope to not confuse the issue, but I think this isn't entirely correct. GPL
only covers distribution, so if you distribute an application linking to
commercial Qt, the GPL does not allow linking GPL PyQt against it. However,
if there is no distribution, then it is perfectly fine.
For example you(personal or business) are currently using GPL Qt and PyQt,
then you decide you would like to use some of the features of ActiveQt, so
you buy a commercial Qt license. It is still fine to use GPL PyQt. However
if you choose to distribute the software(whether free or for a fee), you must
then either buy the commercial PyQt, or distribute a version that links to
the GPL Qt and not provide the ActiveQt functionality.
