Some breakdown and comparison over the years https://meta.m.wikimedia.org/wiki/Wikimedia_Foundation_salar...

$67m is quite low for a tech organization. Wikimedia pays below market rate for every position. They have quite a lot of staff for that amount of money.

$67m is around 300 software engineers at a bay area company, only considering salary. If equity is included, it's probably closer to around 200 engineers. Of course, there's other employment costs, so in reality it's even fewer employees than that.
