John, It isn't just the $900 per year for the ADCD OS license. You can’t legally get ADCD without the ~$5K yearly cost of the zPDT dongle and Linux hardware emulation layer to run the OS's. That's the real kicker.
OTOH I wouldn't be surprised if bad-actor state security organizations (or US security skunkworks organizations for that matter) haven't already reverse-engineered the zPDT dongle for their own nefarious uses. Paranoid? Maybe, maybe not.

The current zPDT seems to be for "home workers" of an ISV or maybe office workers for a 2-3 person operation (IDK). I just looked and it is $900/yr U.S. . I can afford that. But I'm not an ISV. And I don't want to "bother" with whatever it takes to convince IBM that I am an ISV. Mainly because I'd be lying through my teeth. And I'm not a scum politician, so I'm adverse to doing that. {yeah, I'm being tacky} -- This message and any attachments are intended only for the use of the addressee and may contain information that is privileged and confidential.
