Why do people care about noisy auto focus in lenses?

- If you're shooting a film with dialogue, then you'll probably use a microphone pointed at the actors. The end result will not be affected

- If you're shooting an outside scene, you'll bother no one with the sound anyway, and the resulting photo will not be affected

- If you're shooting a concert or something, no one will hear it, and again, the resulting photo will not be affected

- If you're silently shooting withdrawn animals like a sniper, you'll probably focus beforehand, switch to manual and just wait for the right moment to click. Why risk the added time to auto-focus when a bird or mouse something flies into your scene and hops around? Again, if done properly a noisy motor doesn't effect the photo

Why is this a factor handled in lots of reviews? Who gives a shit?
