> Perhaps not, but that's not right to repair. Pretty much everything in any modern smartphone is completely proprietary.

That's exactly what right to repair refers to! Companies can't stop you from taking a screwdriver to an object in your possession, the issue is that by using non-standard components they make what should be an easy repair extremely difficult if not impossible without going through them, allowing them to effectively prevent repair. Smartphones are the poster child for lack of right to repair.

> That doesn't even suggest to me that it's wildly proprietary, just that it can't be found anymore.

If it wasn't proprietary, it would be able to be found. Off the shelf battery connectors are produced in the millions and remain available for decades. The whole reason for this issue was that instead of using one of those, they went with something non-standard that a person couldn't get, and despite having them on hand they wouldn't give one to the user.

> This also isn't right to repair.

Again, it is.

> In fact, it probably doesn't help much at all: a sufficiently specialized part on a specialized medical device is going to be so niche that the cost of an aftermarket part will be huge.

So long as the cost of replacing the part is less than the cost of replacing the entire system that depends on that part, it still makes sense. Aftermarket manufacturers specialize in making such one offs.

> The device was supported for the regulatory limit of five years, and the owner has been using it for ten.

The FDA doesn't have regulatory limits for how long products can be supported, it sets minimums for how long products need to be supported. The company chose to drop support after 5 years, it was not barred from providing support afterwards. If you read the article, the company both did provide the support requested and issued an apology for not doing so sooner.

> Assuming they did give three years of support after discontinuing the product, it's now two years beyond that.

Part of that end of life process is notifying operators of the devices that support will be ending, giving them time to get spare parts as needed. There is no indication that this was done.

> For a product only approved to be sold for five years by a regulator,

Again, not what happened.

> I think the fact that the only piece that couldn't be serviced after double that time is a battery connector is pretty impressive

There is no indication that any other part has been successfully serviced in that time period. The battery connector was the part that happened to fail, and when it did bricked the system. Other parts may have failed in a way that didn't render the system inoperable, and other critical components may have yet to fail.

> I'm not sure how much more you could possibly ask from this company.

Designing products to utilize source-able components and making specifications for custom components available after you stop manufacturing them are two things that can be asked of any company. It costs essentially nothing to do either. It even benefits the company to do so - using standard components reduces production costs and decreases supply chain risk, while publishing part specs allows a company to offload continuing support costs onto third parties.
