I would like to add that Control-IQ still underperforms open source DIY artificial pancreas systems like Loop (https://github.com/LoopKit/Loop).
The guys that built Loop and the Riley Link (https://getrileylink.org/) (bluetooth to RF adapter relay to control wireless pumps that were reverse-engineered) are heroes.
One downside to this announcement is that this may become an excuse to stop open-sourcing features to Gitlab CE.
We (Debian) use Gitlab (salsa.debian.org) but we wouldn't switch to the free Gold/Ultimate version because we don't want our infrastructure to run on proprietary software.
It might be that the majority of free software projects accept to use the free subscription and therefore lower the pressure to add new features to Gitlab CE.
I think that is is best to open pull requests to Gitlab instead.
You may object and say that it is a bit lame to re-implement something that is already in the paid version. However, it is best than re-implementing everything from scratch.
Also, I have heard that Gitlab is open to open-sourcing features when you show interest to have it in the free version.
The guys behind the Gitlab company move the community edition pretty fast too, possibly faster than what we would achieve by duplicating efforts.
However, as I mentioned in another comment (https://news.ycombinator.com/item?id=17241209), this may change because the new free Ultimate/Gold subscriptions could become excuses to stop open-sourcing features to Gitlab CE.
