It's becoming more and more common to see Apple devices in series and movies, as well as those produced by Apple more often. It's a way of advertising used by many companies and now, in the case of Apple, we know more.
As director Rian Johnson participated in the interview Bad taste, Apple is letting its devices appear on the scene, and iPhones are well-known the company does not want the bad guy to go out in public using an iPhone.
Bad people can't carry an iPhone
Apple has always been known for its strict rules, if you want to use its devices you have to go through the hoop. According to the company itself, Apple products should only be displayed "In a very good way, in a way or context that perfectly reflects Apple products". And this is just what happens with the bad characters in the movies.
"And another funny thing, I don't know if I should say this or not … Not because it's like a leap or something, but because it will bother me in the next mystery movie I write, but forget it, I will say, it's very interesting..
Apple … they allow you to use iPhones in movies though, and this is especially important if you've watched a secret movie, bad people can't have iPhones on camera.
So, oh, nooooooo, every filmmaker with a bad boy in his supposedly secret movie wants to kill me right now".
No doubt this would be destroyer full movie, if you're watching a secret movie or series and don't know who this really bad guy is, If everyone uses an iPhone except one, you'll know who they are. The idea has been on the table for many years, with many claiming that they were the only good people using Macs while bad guys always had a PC. Now that this is confirmed, Apple does not want to connect their devices with the bad ones.
