The article is weird - the title is what it is, but there's barely anything inside of it that mentions anything about it being legal, except for a single sentence, with the rest of the article just saying how it works. Digging a bit deeper (by looking up the pod on a search engine lol), it doesn't seem that the pod is actually approved or made legal or anything, but it was apparently supposed to be made open-source in 2019, in 2021 the creator only sought legal advice about the pod and after that - no more news. Maybe I missed something though.

tl;dr the article's title might be misleading
