As have most. Some, like Tesla and Apple, even have factories there!!!

Apple has connections so great that United even introduced a whole airport leg SFO-PVG just for them (unless it's an urban legend).

I was curious, so I researched it (aka prompted ChatGPT). SFO-PVG was established in 2000, long before Apple offshored all of their manufacturing to China. An article from the time describes it being something that was in demand among Silicon Valley in general[1] rather than Apple particularly. In 2019, United revealed that Apple does spend $35 million/yr on that single route, averaging 50 seats/day[2], so I suppose that's the source of the legend.

I think this was SF to Chengdu. From: https://www.reddit.com/r/whoathatsinteresting/comments/1tspz...

As CEO of a company that sells GPUS, it seems like the more people he's able to sell to the better.
