Disagree. Open source as a development root has a specific definition.
No, this so called "specific definition" you speak of, was piggy-backed onto what had been going on for quite a few years before when OSI was formed.
Source for 3.1 is now a point of reference, a leaked document in the public domain. No more than that, it is too much of a jump to declare it as a true open source OS. It isn't.
So are you saying AmigaOS 3.1 sources are now public domain?
Why? Copyright rests with the copyright holder until 70 years (probably longer) after expiration of the copyright holder.
That depends where you live. In the same way certain countries decide to ignore treaties they have signed regarding human rights violations, the Geneva convention, the treaty of Rome, the Paris Climate agreement etc, some countries also chose to ignore copyright treaties like the Berne convention. I can assure you that copyrights are ignored in most of the world.
It becomes Open Source 70 years after CBM filed for Chapter 11.
Hardly. First of all, CBM barely had all the copyrights themselves, a lot of the components of OS3.1 was licensed in the first place, and some of if legally dubious already. It is unclear whether all the rights to those licenses were transferrable, or whether they were CBM strictly. As Thomas here can confirm, CBM themselves were not exactly saints when it came to copyrights.
If in the meantime, it gets wholesale conversion to native HEX code, as opposed to being compiled C, then the translated version could be declared as Open source (translated works are not a technical breach of copyright, although they could be used as the basis for an IP infringement legal case - extremely unlikely). However, such a translation would have the same Amiga problem - it would require a custom ROM version for each basic Amiga type. NOT a small task.
I did not understand squat of what you tried to communicate there. You are saying that if you dump a binary as hex, you can declare that hex as "not a copy"? Then there has not been a leak of the AmigaOS 3.1 sources, as it was spread as a tar.gz file, which obviously has no similarities with the original works, but merely is a file describing how the original sources must have looked like :laughing:
