This is a move that I would personally encouraged because it sends a message to people that the crypto world is not a free for all that you can come in because you have a special skill or smarter than other but you believe that those skills can not be put into better use than to steal people resources and make them cry just because they wanted to earn legitimate inflow of a platform that they have been provided such opportunity. Kudos to the United States government agencies for taking this initiative.
They have no jurisdiction in Russia. We've seen numerous times how the Russian government denied extradition of their citizens to the EU and the US, so this decision by US government is just for show. It will all change if those hackers are dumb enough to travel to the EU and get caught there, but as long as they stay in Russia they'll rather get employed by the secret service than sent for trial to the States.
