Mozilla Corporation doesn't accept donations. Most of its income comes from Google. The parent foundation gets about half its income from the corporation. The rest is mostly corporate and individual donations. Even worker owned companies elect a president or CEO to manage the company day to day. Valve has less official hierarchy than most companies. It doesn't run entirely by consensus though. People who worked there have written about the unofficial hierarchy.
