I am pretty sure this is not what the people who made the seal are talking about.
Read their site. They're talking about "pictures, movies, audio (music or voice action) and writing". Code in itself, especially for simple tasks like basic game logic, is not art, and I am saying that as a developer.
I am still very doubtful AI can write quality code, but I really don't care. I am sure it becomes a mess if you try to write very complex systems, but that's not the case for most games. And if AI generated code is good enough for your use case, good for you.
I am not "assuming" anything on anyone's behalf. There is a clear difference that's practically not even about AI at this point.
You're not stealing from a programmer by frankensteining bits of their freely available code. As someone else said, it's basically stack overflow with an extra step. There's no secret sauce in coding, you can evaluate code quality, you can exchange tricks and techniques, but you're not expressing yourself through code.
However, if you take bits of one or several cultural products without the creator's consent and pass the whole thing as your own, that's called plagiarism, and this is a special thing for a reason.
For AI, I don't think anybody cares about a random beginner using it as "crutch". People care about big entertainment companies deciding they need 90% fewer artists because AI does "good enough" (even when it does quite poorly, and even when it's trained on the work of people like the ones they're replacing).
