Except in this case the middleman added thousands of dollars to the cost without adding anything of value: not curation, not discovery, nothing. Without this middleman acquiring an expired domain would have been whatever the nominal registrar cost (somewhere between $10 to $100 or so per year for a domain)
Useful middlemen do serve a role and add value. A parasitic middleman just extracts value without adding any value anything in return.
