IT doesn't always hear the grumbles, hidden away as they frequently are behind a ticketing system; the help desk technicians who do hear the grumbles aren't always informed of the "why" behind certain policies, and don't have the time or inclination to go look them up if they're even documented; and it's a very unsatisfying answer even if one receives a detailed explanation.
Information loss is an inherent property of large organizations.
On a more micro level, I find it very hard to write good documentation. I always forget something that once pointed out seems obvious. Or worse, the reader is missing some important context that many other readers are already privy to. Not to mention, some people don't even seek out docs before acting.
I imagine this gets amplified in a large org. The docs are lacking, people might not read them anyway, and you get an explosion of people who don't understand very much but still have a job to do.

That's such an interesting axiom, I'm curious if you would want to say more about it? It feels right intuitively - complexity doesn't travel easily across contexts and reaching a common understanding is harder the more people you're talking to.
