As others have said it’s to protect the integrity of it. If it’s being used in movies and TV shows then people get use to hearing it and it loses its impact and people won’t listen to it when it is real and just ignore it as being a movie on tv or something like that. Even if it makes sense in the context of the movie you are still using something that is only meant for emergencies and that’s it. The more it gets used outside of that though the less impact it has and so emergencies won’t be listened to as much or brushed off and ignored as not being the real deal.

But if I'm watching a movie then I know it's not really breaking in to deliver an actual message. The concern would be with live broadcasts. I suppose airing a movie on cable you might have to edit that, but in a theater or on a home edition it shouldn't matter.

I already am desensitized to it because the tornado warnings on the radio use the same sound and the listening area of the radio station is such that I hear warnings for folks three counties away which does not affect me in the slightest.

Others may not though. The point remains that it should never be used except for emergencies and as others have pointed out this tone can trigger other things to happen as well which can then in turn create an emergency.

Well obviously not because you still recognise it and know it to be in use for an emergency. You aren’t desensitised. Just because you may not react doesn’t mean you are desensitised. You still know “that’s an emergency”. If it’s being played all the time in movies and tv and such you eventually hit a point where you stop thinking emergency and think “eh just a movie”. Your brain stops recognising it as an emergency sound and as just a sound that’s recognisable but not anything to worry about.
