The main guy in charge is a scam artist
The former Walgreens CEO who partnered with the scam artist invested $140M in Theranos, and is therefore a complete dipshit
They don't even make the screens themselves
The scam artist is serious apple fanboy, and asked designers repeatedly to make the giant screens "more like an iphone"
The scam artist wanted the doors to respond to voice controls
The doors frequently just didn't work
When the doors did work, they often didn't actually show what was inside of them because whoever set up the screen's images remotely had put the wrong things on it
The ads didn't even make money
Apparently fridge doors aren't standardized so they can't be used anywhere else now that Walgreens backed out of the deal, and there are $50M worth of panels sitting in a warehouse
Walgreens is now trying out their own in-store screens

And these absolute fucking buffoons have more money than you or I will ever see.
