Abbott Labs kills free tool that lets you own the blood-sugar data from your glucose monitor, saying it violates copyright law

Abbott Labs makes a continuous glucose monitor -- used by people with diabetes to monitor their blood-sugar levels -- called (ironically, as you'll see below) the Freestyle Libre.

Diabettech is a hub for helping people with diabetes manage their health, including by building "artificial pancreases," through which a glucose monitor is connected to an insulin pump, with software in between that measures out small insulin doses that respond in real time (or even predictively) to changes in blood sugar. These can be significantly better than manual interventions for managing blood-sugar for people with diabetes, and can avert life-endangering, life-shortening, and/or quality-of-life reducing blood-sugar spikes and troughs.

The admin of Diabettech posted technical instructions and code for extracting your blood-sugar data from the Librelink so that you could use a different "listener" app with your data, or even connect it to an insulin pump to create an artificial pancreas loop. In particular, it allowed the free/open Xdrip diabetes-management tool to access Freestyle Libre data.

In response, Abbott Labs used US copyright law to have the project deleted from Github, censoring Diabettech's code and instructions. In its takedown notice, Abbot's lawfirm Kirkland & Ellis LLP (a huge corporate firm) advances several alarming arguments about projects like this.

First, they say that creating a tool that interoperates with the Freestyle Libre's data is a copyright infringement, because the new code is a derivative work of Abbott's existing product. But code that can operate on another program's data is not a derivative work of the first program -- just because Apple's Pages can read Word docs, it doesn't mean that Pages is a derivative of MS Office.
