To take a global perspective: Would you be happy to donate to charity that uses the money to pay executives 10x-100x your salary?
It's not really a business.
Non-profits shut down all the time. If you're concerned about a lasting impact you'll pay for a talented executive team.
The biggest set of responsibilities charites I didn't list is sales (aka donations). But Wikipedia doesn't do more good work (as donors think of it) the more money they get. It doesn't scale up much that way.
