Ransomware doesn't have to be illegal in North Korea to convict a North Korean who did it, either in absence or with extradition, in the country where the damage was done

With Alphabet being from a country with extreme capitalism, the comment you're replying to seems applicable no matter where the viewers are (regardless of whether I agree with their viewpoint/outlook). YouTube's owners can choose to block or prosecute whoever doesn't comply with their terms. Not saying that's likely, just that: this isn't a matter of needing to be on the American continent

Edit: perhaps interesting to realise that, conversely, laws in North Korea might make it illegal for Alphabet to have certain terms if they want to serve consumers in their market. (A better example here would be EU with copyright legislation that makes it illegal to sign away your moral rights, for instance.) It works both ways and both could legally prosecute the other at the same time and both win in their area! But with YouTube being able to gatekeep the content here, one has more power than the other..
