replaced all of their vending machines with machines that require me to install an app(!) to purchase a product

I saw this at a Simon mall recently.

I took a picture of the machine. Across the front of the door is a banner which reads:

  1. Scan the QR code
  2. Create profile
  3. Scan again to unlock door
  4. Close the door
  5. You're one drink closer to a free drink!

I'm not going to jump through hoops like a circus animal for a Mr. Pibb. I used the water fountain instead.
