Parag has around 3900 employees. Wikipedia has around 550. Around 7x multiplier.
$30m / 7 = ~$4.3mil
Sundar has around 135k employees. 245x multiplier.
$250m / 245 = ~$1mil.
$350k seems like a steal no matter how you put it.

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.)
