Wikimedia Foundation (2019): 291 employees, $56M salary costs.

Less than twice the US employees, more than five times the salary costs. (Both orgs also have some non-US employees included in the salary costs total, but they are a small minority of the staff.)
Salary costs don't need to be looked at as something to aggressively push down. You can treat your employees well while still being a non-profit.
(Though I'm not claiming wikipedia treats their employees well, I have no idea.)
You can just keep moving the goal posts every time you get proven wrong.
Also, you were complaining about Wikipedia being in the US/SF, when the Internet Archive is also in SF.
