did you mean to reply to my comment? if yes, can I ask you to explain what do you mean by assumption? where is that coming from?

regarding WMF (and other non-profits, like Mozilla), this is a well-known phenomenon - regarding C-suite compensation (it's usually about risk aversion, and that the board or whatever foundations have, is also usually sitting on other non-profits, and rarely they optimize by moving to the cheapest place and hiring folks for much cheaper, etc)
