A good point made elsewhere about the leaks.
There's a whole Chat Group of 10-20 people involved who didn't report him when he started sharing the data, probably encouraged him and discussed it - and some who then shared the material on other servers/sites. All of whom have also committed federal felony offences.
I would imagine there will be lots of them frantically explaining things to their families and seeking legal advice whilst sweating waiting for a loudhailer call to back out if the house with their hands behind their backs.
And no, the FBI won’t treat them as just misguided kids…
