I was architect leading all things Observability at Red Hat until 3 years ago there was an absurd amount of support for this project internally I never understood it either. But there were huge amounts of customer support, sales and engineers who adore this thing, I genuinely don't understand the appeal when we had next level cluster-wide Observability supported on and off OpenShift.

Even being in a leadership position and basically competing within Red Hat against this, I found no answer to your question.
