The lawyers are arguing their only intention is to set precedence in online identities and the regulation thereof. Pretty much Mueller's team is creating these indictments against people/companies that they expect won't appear to challenge the case so when it goes unchallenged the ruling/s stand in case law. They can later be referred to when they go after who they really want to go after.. The American people.
They are going to lose this case and they know it.. That's why they indicted an individual on pretty much the exact same thing last week with some tweaks and that case will likely go unchallenged.
