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.

Rather crucially, the license itself does not say that you have the right to the source code. It is only the separate written offer which gives you that right. If you did not receive such an offer, you don’t have any right to it. But then, the company has already, unquestionably, violated the GPL, and the company can be sued immediately. Specifically, you don’t have to first ask the company for the source code! The lack of a written offer is in itself a clear violation.

You were right up to this point. Medical devices requiring a prescription must be obtained via specialized suppliers, like a pharmacy for hardware. These appliances are not sold directly to end users because they can be dangerous if misused. This includes even CPAP machines.

In theory, that written offer only needs to go to the device suppliers. Who almost universally have no interest in source code. When the device is transferred or resold to you, it need not be accompanied by the offer of source.

If that was true, anyone reselling an Android phone could open themselves up to legal liability. Imagine your average eBayer forgetting to include an Open Source Software Notice along with some fingerprint-encrusted phone.

That’s only an appeal to ridicule. If those are valid, here’s an opposing one:

If this is not true, then any company can violate the GPL all it likes just by funneling all its products through a second company, like a reseller.

Here's an appeal to the law, the doctrine of copyright exhaustion (also known as the first sale doctrine) dictates that copyright is exhausted upon the first sale of the device (i.e. to the distributor) and they have no rights to control or prevent further sales.

That the GPL potentially fails to achieve what it intends to is neither a legal argument, nor particularly surprising.

Wouldn't that imply that end-user license agreements are all unenforceable because the software was sold through a retailer, and even if it wasn't you could just a get a secondhand copy?

By my understanding EULAs are based on contract law and having a clickwrap agreement that requires you agree to it before using the software, not copyright law. Except perhaps to the extent that copyright law would prevent you from creating a derivative work that doesn't require you to agree to that clickwrap agreement prior to using the software.

		How does that solve it? Alice buys the software, clicks "agree" so that it runs and then sells it to Bob who uses it without ever agreeing.

This is false. The person transferring the device must either pass along the offer they received (GPLv2 clause 3(c), and only if performing non-commercial redistribution), or pass along the source code (GPLv2 clause 3(a)).

		By my understanding under US law first sale doctrine means that 3 (both (a) and (c)) doesn't apply, copyright has been exhausted and the intermediate party here doesn't need a license at all to sell the device on. Even if you want to argue the GPL is a contract and not just a license the intermediate owner has never been required to become a party to it. Even if for some reason they agreed to the contract - and somehow it was a binding contract despite the complete lack of consideration - it seems unlikely that the courts would interpret 3 to apply because reselling a device isn't "distributing" within the meaning of copyright law because of first sale doctrine.

My Android phone does come with an explicit written offer of source. It's in Settings>About>Legal.

It's a medical device that requires a prescription. You can't buy it off the shelf. They're not distributing software to you either. You must go through a medical equipment supplier who transfers the device to you after insurance has paid for some or all of it.

For the same reason you can't find an airplane entertainment system in the trash and call up the company and demand source code.

It doesn't matter what form it takes. Compiled binaries of GPL code are being distributed. The recipients of that binary are entitled to the source of the GPL portions in a usable form:

  "The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable."

The GPL here doesn't extend beyond the kernel boundary. Userland is isolated unless they have GPL code linked in there as well. If they were careless about the linkage boundaries then that's on them.

The recipient of that object code is the medical device supplier, not the end-user.

It's subsequently transferred to you after presenting a prescription, without any accompanying offer of source code.

In other words, assume you are the second owner in all cases when it comes to certified medical equipment.

AFAIK if you find an Android phone in the trash, you are not entitled to source either since you never received the offer of source during a purchase transaction. You know that little slip of paper you toss as soon as you open some new electronics that says "Open Source Software Notice".

		> In other words, assume you are the second owner in all cases when it comes to certified medical equipment. By that logic, _any_ company can effectively ignore the GPL constraints by just selling it to a reseller, first; one that they have a contract with to _not_ offer the source code when they re-sell it. It is my understanding that, if I use GPL in my code, and I distribute it to someone that then re-distributes it to someone else... the GPL is still binding. I don't see why that wouldn't be the case with hardware using GPL'd software.

		So when I buy a product with GPL code via Amazon, Amazon is the one with the rights to receive the source? That medical supplier is getting paid via the medical coverage the end user is paying for.
