Hopefully, someone (maybe me) will step up to plate and maintain the Debian fork of CDR tools again, for Schilling’s memory if nothing else (and to fix bugs, such as the issue with post-2027 CDR images [1] which I have already fixed).
Aside form the licence stuff already linked there were also endless flamewars on how to specify devices when invoking his tools. Schilling was a proponent of SCSI-adressing, and pretty much everyone else wanted to use /dev.
Very sad to hear this news. RIP.
