I think the title implies a causal relationship between the two events.

Edit: In this thread:

> I wonder how the arrest went down, why he took a plea, what the details of his presentation were

>What if he did the exact same presentation in youtube, and in NK they saw that presentation?

Well yes, the executive summary of the article obviously tries to make this look like the US is punishing a freedom researcher for saying things a ten-year old knows:

> The US sentenced a crypto researcher to five years in prison after he presented at a blockchain conference in North Korea.

> Prosecutors say Virgil Griffith, 39, undermined US sanctions imposed on North Korea.

> "The most important feature of blockchains is that they are open" Griffith said in his presentation, according to prosecutors.

there are certainly others commenting on this post who didn't read that way. They're posting as if he was literally sent to prison for just talking about crypto.

Yeah, the author of the article could have just as easily titled it "US sentences crypto expert to 5 years after multiple conversations on evading sanctions".

You can draw your own conclusions as to why they went with the title they did.
