This is the first time I've heard of the "Librarian of Congress" weighing in on DRM. Is this a normal thing that I've somehow missed?

Yes. As the article says, copyright law has a provision whereby the Librarian of Congress can create exemptions.

Pretty smart actually, Congress not trying to enumerate all small details itself.

(section 1201(a)(1) of title 17, USC)

I think the risk of death is probably overstated, as these people have often gone decades without a CPAP, and lived just fine.

That's not entirely true. If you mess up you can end up rebreathing your own air in the tube.

It has small holes that are supposed to allow fresh air to mix in even if the machine is not providing any. But they are small.

If you are a normal sleeper you would normally wake up and remove the mask if you feel suffocated. (For example a power outage.)

If you are with someone who uses such a machine you can test it - unplug the machine, and see how long it takes them to do something (wake up, or remove the mask in their sleep).

High RDIs/AHIs are directly linked to orders of magnitude higher risk of heart attack (and I think also strokes).

Epidemiologically speaking, sleep apnea is deadly, if untreated.

I believe these were introduced under the DMCA in '98?

Maybe a badly configured CPAP machine is worse than nothing at all?

The article says the data they collect include something called "mask leak rates". That means the machine has an airtight mask and could in principle suffocate you if it malfunctions.

Ummm... no. If the CPAP machine fails, you'll just start sucking air in the holes that are normally used to expel your exhalations. (When you exhale, the air goes out through these vents, not back into the machine.)

It's significantly less airflow, and will cause you to wake up, but it's not going to suffocate you.
