Even using a nonfree program to develop free software in general is better to avoid. For instance, we should not ask people to run Windows or MacOS in order to make free applications run on them. As developer of Emacs and GCC, I accepted changes to make them support nonfree systems such as VMS, Windows and MacOS. There was no reason to reject that code, but I did not ask people to run nonfree systems in order to develop it. The changes came from people who were using those systems anyway.
