The Linux Foundation has received the most revenue amongst all of the free software and open source non-profits and directly pays its leader the most, but the highest compensation of any sort is still being received by Mozilla Foundation Chair Mitchell Baker, along with her CTO Colleague Brendan Eich.

But Zemlin is not the highest-paid non-profit leader in the FLOSS community: the Mozilla Foundation generated the highest compensation levels for Baker and Eich who, while receiving no direct salary from the Mozilla Foundation, were compensated $589,953 each from "reportable compensation from related organizations" and "estimated amount of other compensation from the [Mozilla Foundation] and related organizations."
