So they are creating one of the "world’s largest data centres" near the North Pole and filling it with 18000+ Jupiters, just in case they need to give that hashing power to their neptune customers if there are any delays. Very thoughtful.

And if they do deliver neptune on time, they'll just send these 18000+ Jupiters to be melted down as scrap metal? No need for these any more and we wouldn't want to break our 5% promise.

Nothing wrong here, seems legit.
