Throughout the episodes, there are several scenes that play out in a similar
fashion:

> _Static is heard and a diary's contents are updated to reflect the updated
> future._
>
> Person 1: "Did you hear that?"
>
> Person 2: "There must be another diary user nearby"

But sometimes the things that alter the future are incredibly trivial, (like
travelling to a different floor on the elevator, or not eating a salad) and
theoretically anyone should be able to do them. The main reason the diary
users change the future more often is because they can see certain events in
advance and consciously decide to change them, but other than that, they are
visibly no different from the rest of the population.

Everyone seems to have free will, and so everyone should be able to make a
spontaneous decision and affect the timeline. For example, Yuki altering the
future by opening the door at Yuno's house was down to his curiosity alone and
not related to his diary, so surely a non-user would have altered the timeline
in that same scenario.

Granted, for a diary to display the altered future, it has to correspond with
that diary's output (e.g. something in close proximity to Yuki, something
affecting an escape for Ninth), but that alone doesn't isolate changes to
_only_ other diary users.

So why are the diary users so confident in proclaiming the proximity of
another diary user when the future changes? Why couldn't it just be a regular
person altering their schedule, coincidentally coinciding with the user? And
doesn't Akise change the future (as a non-user) in chapter 14 during the coin
game?

Why is altering the future limited to diary users?


The future only changes when a diary owner acts against the "reality" which
their diary foretells. So the future for everyone is predefined, because they
already decided if they want to eat the salad (but they don't know they did).
Only if you know for sure that the current future contains you eating a salad
are you able to change the future.

EDIT:

About the Akise thing: No, Akise didn't change the future. Yukiteru's diary
never really tells the truth. It just tells what Yukiteru is/was/will be able
to see. (It was the same thing when that little kid, Fifth, attacked them.
Yukiteru was in the toilet and his diary didn't "say" anything except that it
was quiet at the toilet.) So, Akise won the coin game, but he told Yukiteru
that he lost, his diary will "think" he lost even though he didn't.
