I don't know, I understand the advice and I guess that's probably one of the reasons Loop (https://loopkit.github.io/loopdocs/) is not on the App Store. If they had turned their project into another data-logging platform we wouldn't have commercial closed loop systems.

Thanks for the link. Yep - exactly, they took a leap, but importantly didn't release a full product / package on the App Store, or charge for features. This falls much more into a grey area, but is clearly DIY, and demonstrates demand/need for the commercial / regulated systems.

Especially when the problematic features are charged for, it gives the recommendations / suggestions an air of legitimacy which could be dangerous.

A lot of the research from Loop and AndroidAPS is used in commercial closed loop platforms; many of the people working for these open source utilities also work for medical companies.

So you either get lucky and your doctor can prescribe you a commercial loop, or you compile one from source.
