The Wikimedia Foundation has also just been fundraising in India and South Africa, again asking people there to donate so Wikipedia stays online for them, ad-free, subscription-free and independent.
None of these executives have anything do with the Wikipedia content. All of that is written by unpaid volunteers in their spare time. When Wikipedia first became a top-10 website, the Wikimedia Foundation had less than a dozen staff, and annual expenses of $2 million. I am not saying lets go back to that; I'm only saying this to make the point that the success of Wikipedia was not dependent on highly paid executives. It happened when there weren't any. The main value of the site comes from the volunteers.
Most in-demand, skilled labour is much more pricey than what the average person makes.
Imagine you were asked to donate to "keep the animal shelter open", and went you went there you found that they were using gold water dishes for the little critters. You would be within your right to complain. You thought you were donating to keep it operating, but now you find that they're using funds on frivolous expenses. Is there something a dish made out of gold does that one made out of plastic doesn't, to justify the expense? Is there something a $350k executive does that a minimum wage one (or even none at all) doesn't?
Any organization that asks for donations would be subject to criticism if it doesn't optimize its operations as much as possible.
