1. Mitchell Baker is also chairwoman of the board of the Mozilla Foundation and is a founding member of Mozilla, and receives no stock compensation because there is none to give,
2. Google can definitionally outspend Mozilla on browser development and has used that to cement their market position for over a decade now, and
3. as long as Google is the primary source of Mozilla funding, they can (effectively) kill Firefox at any time, and diversifying revenue / building up a war chest of funds is the only defense against that,
just seems silly to me.
As a former Mozillian I don't like the choices Mitchell Baker has made (AI and services are poor plays IMO) but the obsession with CEO compensation at Mozilla has always smelled less like a genuine concern for alternatives to Chrome and more like holding a smaller player to an unreasonable standard.
A more interesting comparison would compare these numbers to the head of Chrome's compensation, and more specifically Chrome's spending and revenue vs Firefox's.
