An org that is highly steeped in kayfabe will structurally resist observability.

Every team will intuit that observability will make them look worse than everyone's current perception of them.

So the team given responsibility for forcing that observability will fail.

Everyone will find reasons to not go along, and to collectively assassinate the observability inducer.

It's diffuse push back (no obvious egregiously bad actor, just a swarm of zombie bad luck) against a single team that's one neck to choke for failure by leadership.

If you're in such a situation, you're stuck in a coordination trap, with no good answer.
