this is much more likely to be a malicious state actor than uncoordinated attacks by random internet idiots

How is this "much more likely to be a malicious state actor"? There is literally nothing about this attack that indicates a state actor.

It’s likely to be a “state actor” for the same reason people like to use the term “state actor”: it’s so much more exciting than the alternative.

ransomware is not a typical attack from a state actor

NotPetya had ties to Russian intelligence, and WannaCry had ties to North Korea. Not saying this is a state actor, just pointing out ransomware is just another tool for them.

How do you know it's not ths Chinese or North Koreans looking for bitcoins? It is documented they do transact in bitcoin on the hacking market a lot.

Being angry at a particular person and wanting to get them killed is really bad but it's something a lot of people are capable of. Getting a bunch of random people killed to make a quick buck is different.
