Why Repair Techs Are Hacking Ventilators with DIY Dongles from Poland

> The Polish hacker told Motherboard that technicians will take a manufacturer’s repair class in the United States, get the required software, then share it widely through Europe. “It’s officially prohibited to share the software,” they said, speaking of the PB840 software. “But if you know someone, you can just copy it and they cannot track it.”

How is it that the software can’t be tracked? Is it because the 20+ year old hardware doesn’t connect to the internet and so it can’t “phone home”?
