What about the very people who ran the operation? They were probably retired law enforcement or some govt intelligence type. I can't think of normal office worker (CPA, MBA types) being capable of the methods described.

They must've been paid pretty highly in part because the higher ups wanted to buy silence from the operatives...

All the methods are NOT assumptions but from internal notes of the company. Pretty amazing. Shouldn't this be investigated by the govt attorneys who go after racketeers? They sold a product that was damaging and did pretty much everything (except physical injury) to try to continue selling it.
