They do have support people in the US and a handful of non-support engineering which is why I said thanks and immediately updated the comment to say "majority" instead of "entire" since it's more correct.
That technicality is less relevant to the main point of the argument.
As of January 2020, they had 2,532 full-time employees. Of those, 1,396 were in the US and 1,136 were in international locations. Within the 1,136 is "more than 700" employees in R&D in China.[1]
A LinkedIn search for "engineer" working for "Zoom Video Communications" in location "United States" shows up 558 results.[2]
Their entire management team is in the US, and of their 17 data centres, only 1 is in China.[3][4]

I mean, from a certain point of view, why not? If you're thinking in terms of 1, they're wildly different. If you're thinking in terms of 1,000,000,000,000, they might as well both equal 0.
Honestly I feel that if you're arguing in one direction or another and haven't checked the facts, maybe it's better not to argue about it?
