They are contradictory enough that you can get dinged on one for following another at review time.
Frugality means putting up with lousy hardware and cramming people into working environments to the point where people start bringing up OHSA w.r.t. number of toilets.
Customer obsession means getting an email about a feature used by a couple percent of users and having to spend a week scrambling because the strategic decision you made (to drop the feature in a major release because you need to get it out) has now been declared wrong. Sev-S was a popular term (S-team being Jeff and his directs).
Bias for action means break extremely important OS features that support multiple products because of pure incompetence. Note that this should really conflict with customer obsession and are right a lot, but oh well.
One thing I found odd was that are right a lot/disagree and commit don't seem to matter if the opposing argument is your manager wanting to do other stuff.
My less snarky response would be that they do spread this stuff around. It has some positive impacts around things like customer obsession, which Amazon is great at. Bias for action can be a good motivator for the right type of person, see something wrong and you go fix it. That said it's not problem free. Frugality is made fun of a lot, because it often goes from sensibly frugal to just cheap.
