Yes, assuming you also GPL your own code (anything that links with the 
GPL'ed PyQt) and thus also distribute your source code under GPL.  Many 
companies do not want to do that.

But that was actually never the issue.  The issue in the past was that 
PyQt's licensing required you to paying extra royalties for those users 
(the people that buy your commercial product) as quasi-PyQt-developers 
if they could script or extend your application.  It was a low fee but 
still got in the way.

But now that problem is solved and you only need licenses for your own 
PyQt developers.
