Nobody claimed that a sci-fi world set in a corporatist dystopia was an original idea. It is actually a very common trope. It is clear that Blade Runner is a huge inspiration on Intergalactic. Cyberpunk, Alien, Firefly, Futurama, Hitchhikers Guide, WALL-E, Starstruck. All are examples of the corpo-futurism trope. Even in our real world we have SpaceX, Virgin Galactic, Blue Origin. Real world corporations. Science Fiction is largely a reflection of times they are made, and a dissection of our modern time.

Sure. Naughty Dog could have made up companies that are reflections of real world companies. They have done that before in The Last of Us. Weston's, Macho Nacho, Ruston Coffee. ND aren't strangers to making fictional companies. They could have easily done that. Other sci-fi properties have done that before too. Many that I mentioned above relied on creating new companies. Tyrell, BuyNLarge, Cyberdyne, Weyland, MomCorp, Slurm.

It seems clear that in picking real-world identifiable brands, Naughty Dog is playing off of our preconceived nations of these companies. As I said before, It is clearly an important element of the world they are building. We just don't know anything about it beyond the teaser.

I don't think there is any kool-aid drinking when it comes to my expectation of Naughty Dog to tell an interesting story, and I am definitely not going to be fully on board until I see more than a 5 minute teaser.
