I can't think of any ports that are in private hands, now that you mention it.
These blowhards don't get that governmental port authorities, either run by city or counties, are who "own" the ports and control them. And even after the sale of P&O, the port authorities will STILL control the ports, run the security and have the OPTION OF SWITCHING TO A DIFFERENT OPERATIONS COMPANY FROM THE UAE-based ONE BUYING P&O.
