I'm taking a beating in another comment (it's one of those ridiculous discussions where everyone can demonstrate how righteous they are), but I listened to the podcast and the argument was that the management company (e.g. not the actual funds) used management fees to pay for their own investments.

Ala the frat bros owned A. A had funds B, C, and D. Investers are LPs of B, C and D. Management fees flowed from B, C and D to A, where it was used for nonsensical stuff.

There's nothing at all illegal about that. If a fund has a 10% of holdings management fee, the fund has zero obligation or "fiduciary duty" to the charged fund holders in how they use that money. They can use it on a mountain of blow, or a room of strippers. Or they can invest in dubious investments. Whatever. If investors don't like the returns relative to the management fees, they redeem.

This whole story is very offputting. The individual is talking about various completely uncriminal emails that he read in podcasts, itself arguably criminal and with profound civil liability. And that's the hero of the story? Eh.
