Interesting, but deceptive. Those are, as noted, "Key Employees and Officers." I just assume most employees with the title "Software Developer" aren't making over five times what Moxie is making.
Your number seems to be coming from a very small sample size (single digit N?), and GP's link is only about "key" employees like CxOs, VPs and top-ranking engineers.
I wonder what a median rank-and-file employee at these companies make.
