Sir,
Understood! Your points are well taken. We are a VMware Academic partner. And as I mentioned in my original reply - I work/teach at a Community College and running macOS on ESXi is done for training students how to support & integrate macOS. While I don't have specific permission for this setup, in education here in the US we have a lot of legal latitude & flexibility as to what we can do in educating and training students.
Best Regards,
Randy Graves
