I don't think it's any of that to a significant extent. Big companies just have thousands of processes, and the body count is just what's needed to sustain all of those processes. You see the same thing in government. Yeah, 50 people can do the work of hundreds because they aren't having 6 meetings with 6 people each to propose, implement, evaluate, review, and commit the font change to the help page, plus employing all the admin staff to support those people. Big companies are.
