He is in a position to be asking for source code. BMW did not " a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, "

or do something reasonably similar ( point people to the source code site from their car, etc). Instead, they made a written offer. Written offers must be valid to any third party. Not just to people you give binaries to:

"b) Accompany it with a written offer, valid for at least three years, to give any third party, ... a complete machine-readable copy of the corresponding source code"

(emph mine).

If he doesn't own BMW car, he didn't receive a written offer and can't really act on it.

You have to refer to actual written offer made to one of their customers. The argument that "I didn't see the written offer, but I believe it exists" doesn't seem very convincing.

edit: "own" is defined loosely here, you may ask a friend for a copy of the offer, or rent a car, or download it if someone publishes it on the Internet. But if you have never seen the offer, I'm pretty sure you're not in a position to enforce it.

"If he doesn't own BMW car, he didn't receive a written offer and can't really act on it. "

This is not correct ;-)

(i'll just point you at the other comment, rather than repeatedly quote the gpl compliance guide in multiple comments)

As far as I know, the people who can enforce it are the copyright holders, if they have evidence that BMW isn't complying with the license. It's irrelevant whether they personally own or have used a BMW car.

If BMW (or anyone) has distributed the code in violation of its license then the copyright holders can sue. But there would have to be someone who's received a BMW car (i.e. distribution) for there to have been distribution in violation of the license.

> But there would have to be someone who's received a BMW car (i.e. distribution) for there to have been distribution in violation of the license.

This is a pretty trivial standard to meet. BMW sometimes sells multiple cars in one year.

Sure. So the question then becomes did they a) fail to include the required written offer with one of those cars or b) not honour that offer for any third party? And the answer to both of those is no.

> he's not in any position to be asking for the source code

People keep repeating this, but I'm pretty convinced that clause 3b of GPLv2 says that the source code must be given to any third party, since 3a and 3c do not apply:

I agree. It's also possible, I presume, to hire a car for the day. You don't need to be the owner of the vehicle, surely?

The whole point of the GPL is to give you the right to fix or improve software you own. It would be extremely rude to reprogram a rental.

Depends. Would it be rude to inflate an under-inflated tire? Or to wash the windscreen? Or tighten a loose bolt somewhere?

I mean, you're right - it's impolite (and possibly dangerous) to reflash someone else's firmware. But considering the regular upgrade path for BMWs is to stick a USB stick into the car, I'm not sure how you can prevent it.

IMO modifying a car you don't own would seem to be illegal, no matter how easy or hard it is to do. You wouldn't go and start swapping out engine parts, would you? Why is ECU firmware any different?

"I made a few adjustments to your brake lines, and I improved your steering system -- I call it 'natural' steering because it works the opposite direction."

I'd think you'd really have to but only lawyers could say something legally convincing about this.

The intent of the "any third party" language is that someone who receives a copy under 3c can invoke the offer. The offer must be valid for him, but unless he received the written offer (e.g. by buying a second-hand BMW from someone who distributed the software in accordance with 3c) he has no real business taking it up (and while BMW must honour their offer if he happens to make the correct request, they have no obligation, legal or moral, to help him make the request the correct way).

No, that's not the intent. At all.

In fact, this is covered square on by the GPL faq:

http://www.gnu.org/licenses/gpl-faq.en.html#WhatDoesWrittenO...

"What does “written offer valid for any third party” mean in GPLv2? Does that mean everyone in the world can get the source to any GPL'ed program no matter what? (#WhatDoesWrittenOfferValid)

If you choose to provide source through a written offer, then anybody who requests the source from you is entitled to receive it."

From your own link: "The reason we require the offer to be valid for any third party is so that people who receive the binaries indirectly in that way can order the source code from you." So yes, that is the intent.

Sigh. Look. they have bad grammar, but i'm telling you what the intent is. Please read the GPL compliance guide: https://www.softwarefreedom.org/resources/2008/compliance-gu...

The example valid offer: "... This offer is valid to anyone in receipt of this information."

"Second, note that the last line makes the offer valid to anyone who requests the source. This is because v2 § 3(b) requires that offers be “to give any third party” a copy of the Corresponding Source."

This changed in GPLv3, which specifically mentions people who possess the object code instead.

It was changed explicitly, see the rationale for the third discussion draft of the gplv3.

The legal implementation is that the offer must be valid for any third party, yes. But the intent is that the offer is for people who received it under 3c, and I have no problem with BMW only doing the bare legal minimum for anyone else.

"But the intent is that the offer is for people who received it under 3c,"

Citation requested on intent.

I have provided evidence this was not the intent, citing things like the draft rationale, etc for the license prepared by the people who made the license. Please provide your counter evidence.

You've already provided the citation! Once again, direct quote from your own link, http://www.gnu.org/licenses/gpl-faq.en.html#WhatDoesWrittenO... : "The reason we require the offer to be valid for any third party is so that people who receive the binaries indirectly in that way can order the source code from you." (where "in that way" is referring to "When users non-commercially redistribute the binaries they received from you, they must pass along a copy of this written offer.", i.e. 3c).
