If you review the thread from the top, you might find the primary question we were discussing from the start before you jumped in is whether the Parallel notice is GPL compliant. Whether Parallel’s notice is definitively and absolutely legally binding on its own and away from the GPL is a nuance you introduced, but it has been answered for all practical purposes by both Ole and RMS. It will probably never go to court or be tested by a judge, partially as a result of what Ole and RMS have said: that the notice is not a license and is not contractual.

There is no dispute about this, and because there is no dispute and because it’s not going to court, the statements by Ole and RMS are the most definitive answer we’ve got, and to date is what people are using when making and acting on decisions about Parallel usage. Both of them have said the Parallel notice complies with the GPL because the notice is not legally binding, so Ole & RMS both were saying more than GNU won’t seek to enforce Parallel’s notice. “Academic tradition” is not legally binding law, and the notice doesn’t reference any other relevant law. The notice is full of legal holes, if you insist on interpreting it as a legal contract. It was written by Ole (not a lawyer) and doesn’t define what research usage would constitute a mandatory citation, nor what happens if the user doesn’t see the notice, or if a citation is inappropriate, or if the citation is rejected by reviewers, among many other possibilities. It doesn’t take a lawyer or judge to see that the Parallel notice is not legally enforceable, and it doesn’t take a legal education to see that it’s not Ole’s intent to enforce it as a contract. He is just asking for citations, in slightly confrontational language.

It would be fair to say that a judge or court, if this issue was ever tested in court, might overrule some aspect of Ole’s or RMS’s stated intent because their language was imprecise and effectively said something different than they meant. Then again, another judge can override the first judge. There’s nothing definitive or absolute or permanent in law, regardless of whether a judges rules on it, and intent does matter in practice. Before this ever goes to court (probably never), all questions on this topic can be (and already are!) answered by non-judges, which is why it’s demonstrably not true to claim this question can only be answered in court or by a judge.

> You should not ask a programmer for a “ruling”.

RMS wasn’t acting as a programmer when he wrote the GPL, btw, nor when he opined on whether Parallel’s notice complies, so in that sense your framing is veering into the hyperbolic.
