Seven Diabetes Patients Die Due to Undisclosed Bug in Abbott's Continuous Glucose Monitors

Seven diabetes patients died and over 700 were injured due to a bug in Abbott's Freestyle Libre continuous glucose monitors that falsely reported extremely low glucose levels. The FDA issued a recall for affected devices. The incident highlights ongoing concerns about proprietary software in medical devices, where lack of public source code and hardware specifications prevents independent peer review by the broader engineering community. A FOSS Android application called Juggluco exists as a reverse-engineered alternative to Abbott's proprietary companion app, though most patients have agreed to Abbott's indemnifying terms of service.
