You seem to be missing their point; they were worried that previously, there was a possibility of their servers etc. being seized for investigation (a la Megaupload) based on these dodgy wire transfers. They believe that in Iceland there is less chance of this happening.

In other words, they believe Icelandic authorities will be more likely to tell the Italian authorities where to go than would the US authorities. This doesn't seem unreasonable.
