Quoting the Riverbank FAQ [1]: Q.
What are the implications of using the GPL version of PyQt? A. To understand your obligations when using GPL code with your application see the GPL FAQ <http://www.gnu.org/licenses/gpl-faq.html>. [1] https://www.riverbankcomputing.com/commercial/license-faq So, using PyQt5 makes you abide to the GPL (v3). A release of Spyder which depends on PyQt5 (which is GPL) would then be considered a combined work and need to be licensed under the GPL too. The situation was different with PyQt4, because of the added exceptions Carlos is referring to. However, these are absent in PyQt5.
