> CGMs (of any brand) are not, and have never been, reliable in the way that this story implies that people want them to be reliable

This has been my impression. I briefly used an Abbott Lingo to help me understand some health issues I was experiencing.

It's always been clear to me (including in the app and documentation) that CGMs are an extremely convenient tool as a first line - but struggle in extreme circumstances. And, let's be clear, if you would generally know if your body is in one of these extreme circumstances. You'd probably be feeling like shit.

That's not to mention the device in question, the Freestyle Libre, is (to my understanding) by far the most popular insulin-dependent diabetes CGM available.

This article is equivalent to calling the Boeing 737 unsafe because it's had the most Full Lost Events while completely ignoring it's flown 238.84M flights (which is basically more than the entire rest of the list combined).

You don’t get many people calling the MAX a good plane.

If you include in the count a new model which arguable should never have been allowed to be called the same plane, then yes, your prior good record looks ok. Over various generations the hull loss rate had come down to 0.18 per million flights while the MAX is at 1.48 per million flight.

How does this relate to the CGM analogy?
Manufacturers update software periodically on these devices, so each new generation is a MAX to some degree.
It's a bad analogy, and the 737 MAX is a bad plane
