This isn't on the people this is purely on the incompetent writing and framing. In the case of ardenweald they already had to forsake their purpose and sacrifice entire glades (yet for some reason they kept parasites like the troll loa around..) for their anima and yet no one bothered to check what the fuck is wrong with no anima coming through. The eternal ones know how the machine of death works, they should know that something is amiss. In the case of the Kyrians you have them flying to Oribos all the time and not a single one thought to report that all souls are being funneled into the maw? This maybe be plausible with a rinky dinky operation that has 10-100 people looking away, but it becomes unbelievable when it's on the scale of all life in the universe. If you want to blame this all on the attendants in Oribos then there should have been covenant representatives constantly petitioning them for an answer, oribos should have been shut and been designed entirely different visually to facilitate this plot. The way it is though, no, everyone can see from a distance that something is amiss.
