alt Hacker News> I then decided to contact Insulet to get the kernel source code for it, being GPLv2 licensed, they're obligated to provide it.
This is technically not true. It is an oversimplification of the common case, but what actually normally should happen is that:
1. The GPL requires the company to send the user a written offer of source code.
2. The user uses this offer to request the source code from the company.
3. If the user does not receive the source code, the user can sue the company for not honoring its promises, i.e. the offer of source code. This is not a GPL violation; it is a straight contract violation; the contract in this case being the explicit offer of source code, and not the GPL.
Note that all this is completely off the rails if the user does not receive a written offer of source code in the first place. In this case, the user has no right to source code, since the user did not receive an offer for source code.
However, the copyright holders can immediately sue the company for violating the GPL, since the company did not send a written offer of source code to the user. It does not matter if the company does or does not send the source code to the user; the fact that the company did not send a written offer to the user in the first place is by itself a GPL violation.

Are you saying that in the general case if you send someone a written offer for something and then don't honour it, you are in breach of contract?
That doesn't sound right to me.
A written offer is not the same thing as a contract.
The written offer with a limited term of three years is just one permitted method of distribution. If an offer was never made then they're not covered by that clause and are bound to comply by other means without the protection of the three year window.
IANAL, but this is my understanding.
What's the consideration in the written offer? Promises aren't enforceable in court. For a contract to be enforceable, it has to be an exchange of something, not a one sided offer.

It should be noted that this is just one of three options that someone who wants to distribute binaries of GPL code can choose from. It's the most commonly chosen one, and one is only available for noncommercial distribution, so the odds are good that this is the option they are using.
The other available option is to accompany the binary with the source code.
That one leads to an interesting possibility where someone could end up with a binary and there is no one obligated to provide source to them. As far as I know this has not actually arisen, but it seems like something that is bound to happen sometime.
Suppose company X decides to make a generic hardware platform that other companies can buy to build their products on. X's platform is basically a small single board computer with WiFi, Bluetooth, dual, USB ports, a couple Ethernet ports, and some GPIO ports. X ports Linux to their hardware.
When X ships a system it comes with an SD card with a Linux distribution installed including their custom kernel. It is configured to boot from the first SD card slot, and then to run a custom login system that looks at the second SD card slot and if there is a card in there it mounts it, looks for an executable on its root name application.exe, and runs that as root. X includes in the box a small thumb drive with a copy of the source code for everything on the SD card.
The idea is that a company Y that wants to make something like a WiFi access point or an air quality monitor can buy these boards from X, put them in a case with whatever peripherals or sensors they need like air quality sensors, write the software for the application, put it on an SD card, and put that in the second SD card slot.
So lets say Y buys 1000 of these systems from X, builds 1000 of their access points or whatever from them, and sells them.
One of their customers asks Y for the source code of the GPL parts. Does Y have to provide it?
I'd say they do not. They are not making copies or derivative works. They are just receiving physical copies from X and passing those on unmodified to their customers. This should fall squarely under the First Sale Doctrine in US copyright law, and similar rules in other jurisdictions.
How about if they ask X for a copy?
X has made copies and derivative works and distributed them. But X satisfied their GPL requirements by including a thumb drive with the source with each board they shipped to Y.
Doesn't seem incorrect if, extra steps aside, the company is ultimately obligated to provide the source code by the terms of the GPL.
In America, maybe this is the case. In Germany, it seems an end user can sue them directly for source code.

But GPL is a contract
I think the distinction you are pointing would be between a gpl licensor-licensee contract, rather than a licensee-user contract.

This is an open legal question, which the Conservancy v Vizio case will hopefully change; in that case, Conservancy is arguing that consumers have the right to enforce the GPL in order to receive source code.
