I mean that if a government "takes the source code" of xxx project to do something, it is fair to release that product under the same license (unless the same license does not optionally allow such a thing, for example BSD licenses / MIT). In the case of the "Petro" cryptocurrency of the Venezuelan government as far as it is known, it was based on the Ethereum source code (apparently they changed at the end). Ethereum is open source (although it has multiple licenses including MIT), I think the "fair" thing is that the source code is released or at least "contributions" from the Venezuelan government, but nothing, Petro is a closed product, you can see on its official website https://www.petro.gob.ve/index.html that the source code is not available, nor do they make references to what was taken in part from free software, I think that is frank "plagiarism" (even though there is a MIT permissive license, at least thank the base project, but nothing) . That's what I meant that the opensource code should not be used for governmental or personal purposes without even mentioning or thanking the original source.
