It's pretty crazy. One thing that people don't realise about type 1 diabetes is that your effectiveness at blood sugar regulation basically translates into years of lifespan: the damaging effects of high blood sugar are cumulative and complications are inevitable, you can only hope to delay them as long as possible (low blood sugar is more immediately life threatening). Insulin pumps were already a huge step change in the level of regulation you could achieve, and openaps is yet another level again, which you can't get anywhere else. I don't fault anyone who uses or develops it, even in the face of the risks or legal penalties.
