They were misrepresenting their enterprises as "churches" and telling their customers to report their transactions as "church donations". So it looks like the fraud, wire fraud etc. charges might stick.
Feds allege that about every unregulated crypto exchange of any kind.
It does seem like this particular business was relying upon legal hacks and obscurity more than following the established rules for financial firms, probably for ideological reasons.
I don't know, this seems like straight up money laundering versus just operating in a grey area of the law. They setup a tax-exempt church and ran over $5M through it. Now I think driving an armored vehicle into this guys house was excessive but I don't think he's innocent either.
