Bit more complicated than that .......................
Whilst its easy to just assume HPE are trying to rip off customers, the detail is actually important. You will find its not just HPE who have these policies, all other vendors will as well.
As someone else has said, its mostly export regulations (not just US ones, every country has them) that are a big part of this! With technology IP it is the technology company who has responsibility for where their products actually end up, NOT the reseller or even distributer. HPE could, and companies do get fined if their product is exported to a blacklisted country.
This is why his defence was a load of baloney, whilst he may own the physical asset so can do what he wants within his own company, he doesn't own any of the IP in that asset and so cannot pass that on with out approval.
They are a by-product of the cold war where the Soviets where trying to use shell companies to get hold of Western technology both to use and reverse engineer, North Korea and other sanctioned countries still try it today. 42k servers would make a nice HPC rig for some nuclear testing .........
The second part is actually more to do with support and end user experience.
To give you a real example, when I worked there we had one customer who had bought 100 servers "on a deal" from a dodgy reseller but was experiencing failures when they booted them up and understandably were very not happy.
On investigating it was found the servers were originally supposed to be part of a shipment into another customer (they bought and paid for their consignment but the reseller ordered 100 more than needed from the distributor) but where siphoned off by the reseller in their integration centre. They put them in a leaky shipping container in a field for 6 months whilst they waited for a buyer, when one came along they stripped the packaging (because it got wet) shipped them to the customer as new (even though the warranty was 6 months in) and then just blamed HP when wet circuity exploded on power up! Cue one p*ssed off customer, a 100 servers that needed scrapping and the reseller walks off with the money ...........
