> Today, many companies basically ban GPL-licensed or otherwise copyleft software projects

At the same time, there are shining examples of commercially used and developed copyleft software like Linux, Blender, OBS-Studio. I doubt there exist many companies that banned really all GPL-licensed software, including Linux.

This shows that the GPL itself is not necessarily a hinderance to commercial use or development. In the end many hardware vendors accepted the GPL as a fact of doing business and opened their drivers to add them to the Linux kernel. With NVidia being the most prominent counter example.
