Well that certainly took an unexpected dark turn.
Pretty interesting article and worth a read, he seems like an interesting character. Based purely off this I'd say he seems to be a pretty unscrupulous businessman who hides behind a veneer of yoga and piousness, but who really knows.
But it sounds possibly more likely someone trying to get back at the company to me. I mean, what’s the marketing value of adding human skulls to your medicines if you don’t tell people about it?
Elsewhere medicines claiming to contain human flesh have been sold on the black market, it’s all pretty horrifying:

Temporarily owning a (second) human skull is legal in some countries under some circumstances. For example more than 5 years after the people passing out, scientific use only, and a permit from the family (or bones unidentified and left in an ossuary for decades). The governments allow thousands of permits each year.
