It says in the article that the person has benefited financially from this. It's not about making open source, I don't know why people are raising that red herring. Implementing a mixer is (probably) not illegal in The Netherlands, putting one in production and setting it up in such a way that you benefit from it absolutely is. I don't believe it's a coincidence that the sanctions and the arrest happened close together, there's likely some coordination there. But it's really unlikely the sanctions somehow are relevant in this case.
