By DC, I just mean a facility that hosts the miners. Whether it is an actual DC, a barn, a shed or a food factory is irrelevant. The relevant point is that HashLord was in control of it, not AM. Also, I would say it's more likely that HashLord is a business entity rather than an individual.
I think your wrong. Jutaral didn't use any company names he just names the roles of all those involved who ever they maybe.
AMHash theoretically involves 5 Parties (Operator, Manufacturer, HashLord, Contract Platform, Contract Holder)
