Yes, indeed

Yeah, sorry.

I can't find any way that would be suitable for me to contact them,
sorry

After looking for some time at
https://forum.zdoom.org/search.php?keywords=commercial&sid=8494f77771bc9efb089cfc0d688adf44
it doesn't seem to mention anything about the
non-commercial-distribution-only data

I studied the source code and didn't find anything that allowed the
disabling the requirement for non-free data, and didn't find any
--disable options for gzdoom itselff, but I don't know much about cmake
(which is used by gzdoom during building) so perhaps I missed something
