As for the list, see [0].
That list doesn't appear to be "legally binding" in a general sense; to me, the way you worded that implies "there is a law saying OSD is the definition of open source in this country" which is very far from the case.
Instead that list appears to be specific cases/situations e.g. how some US states evaluate bids from vendors, or how specific government organizations release software. And many things on that list are just casual references to the OSI/OSD but not laws at all.
You can read more about this at https://opensource.org/pressreleases/certified-open-source.p... or https://www.techmonitor.ai/technology/open_source_initiative... among many other sources. Or a much longer blog post from a lawyer who is active on HN: https://writing.kemitchell.com/2020/05/11/Open-Source-Proper...
fwiw, a non-OSI attempt to trademark "open source hardware" was also rejected for the exact same reason. https://opensource.com/law/13/5/os-hardware-trademark-reject...
there is disagreement on exactly what “open source” means, but generally clear boundaries between open source and source available software in licensing and spirit of the given project. e.g. MIT and Apache 2.0 are open source, BSL is source available.
edit: PERSONALLY, I think if you don’t welcome outside contributions, it isn’t open source; see others’ responses for disagreement on this (it’s not a part of the standard definition)
That isn't true. Open source refers to the ability to make use of the source code if you wish, not the ability to send pull requests. SQLite is open source (public domain even!), but does not accept contributions from outside.
it’s also fine by me if you want to have your own definition; see other comments, I don’t personally 100% agree with OSI’s definition myself
Arguably it is, in the sense that they didn't actually invent the term; there are many documented pre-OSI uses (including by high-profile folks like Bill Joy) saying "open source" to just mean "source available". And OSI's attempt to trademark the term was rejected.
> if you don’t welcome outside contributions, it isn’t open source
That isn't even part of the OSI's definition, so what are you basing this on?
edited my comment —- that is my personal belief/definition
I did mention there’s disagreement —- I haven’t read up on the history and whatnot myself in a while. will have to do some re-reading :)
It's not a question of belief. Maybe words don't mean anything anymore, but certainly legal contracts and licenses do. "Open Source" is a class of licenses approved by the OSI. There are no spirits involved.

Words have meaning!
As far as I can see, your second link (applies to all EU member states) makes no mention of the OSI whatsoever, and uses a definition that is far briefer and less specific than the OSD.
I cannot evaluate the third link (Germany) as I don't speak German and automatic translation may introduce subtle changes.
Because prefixing something with the word "Open" to imply that it would be completely transparent (in any context) wasn't even common before the term "Open Source" was invented. When people do that, they're hoping that the goodwill that Open Source has generated will be transferred to them, and they are judged on that basis. "Open" generally had a slightly different meaning: honest.
> A random "initiative"
And when you play stupid, nobody respects your argument. It's self-defeating.
I can’t say others weren’t using it before then. I can say say that I first heard of Open Source after I’d heard of Free Software.
Like, if people had collectively used the term 23 times through 1996, then 837,000 times in 1997 or whenever OSI popularized it, I’m fully onboard with saying it’s their term.
