The article, strangely, leaves out the name of the project it's reporting on. It's OpenAPS, http://openaps.readthedocs.io/en/latest/ . I use it and have worked on the code. It's a massive health and quality of life improvement over anything that exists which is FDA approved. The core problem is that the FDA-approved devices are optimized not for getting the best result, but for ensuring the manufacturer can't be blamed if something goes wrong. But that in practice means kicking most of the important things to the end user and their physician, who can't do nearly as good a job as software can.
