alt Hacker NewsThis got buried on HN a few days ago which is a shame:

Linus rants that the SFC is wrong and argues that the GPLv2 which the kernel is licensed under does NOT force you to open your hardware. The spirit of the GPLv2 was about contributing software improvements back to the community.
Which brings us to the question: what is this guy going to do with (presumably) the kernel source? Force the Chinese to contribute back their improvements to the kernel? Of which there are likely none. Try and run custom software on his medical device which can likely kill him? More than likely.
The judge's comments on the Vizio case are such that should this guy get his hands on the code, he has no right to modify/reinstall it AND expect it will continue to operate as an insulin pump.
This is about as ridiculous as buying a ticket on an airplane and thinking you are entitled to the source code of the Linux in-seat entertainment system.

It may be the case that when all is settled, the courts determine that the letter of the license means others' obligations are limited to what the judge in the Vizio case wrote. And Linus can speak authoritatively about his intent when he agreed to license kernel under GPL.
But I think that it's pretty clear—including and especially the very wordy Preamble—not to mention the motivating circumstances that led to the establishment of GNU and the FSF, the type of advocacy they engage in that led up to the drafting/publication of the license, and everything since, that the spirit of the GPL is very much in line with exactly the sort of activism the SFC has undertaken against vendors restricting the owners of their devices from using them how they want.
Why is it ridiculous? If the license says you have the right to obtain the source code to software that was distributed to you, then you have the right to obtain the source code. It doesn't matter what your intended use of it is.

As the original Reddit comment explains, Insulet is an American company.
Big disagree, if they distribute the code they’re on the hook for the gpl source, too!
That’s about as ridiculous as buying a plane and knowing you’re entitled to the gpl sources used.

Linus is arguing against a strawman that Conservancy never actually argued. See https://sfconservancy.org/news/2025/dec/24/vizio-msa-irrelev... for details.

I think this sentence is very sad. Not only this is a hard accusation, it is also the primary argument of the anti right to repair movement. An argument that I think is extremely bogus and ill intentioned, and I particularly (like Mr. Rossman) viscerally dislike.
Maybe the primary motivation is a) curiosity, and b) just for kicks to know if they honor the license.

That happens every Tuesday, hardly newsworthy.

It's not like the OEM software also won't kill you: https://sfconservancy.org/blog/2025/dec/23/seven-abbott-free...
There are a lot of people hacking on insulin pumps and they are lightyears ahead of commerce. If you want a very interesting rabbit hole to dive into try 'artificial pancreas hacking' as google feed.

I would trust the people that hack on these systems to be even more motivated than the manufacturers to make sure they don't fuck up, it's the equivalent of flying a plane you built yourself.
