The most hilarious is McDonald's app - it refuses to work without Play Integrity check. I wonder what braindamaged reasoning is behind this. Do they want to position themselves as a bank or something?
Fastfood apps typically offer deals to new customers.
I suspect this is an attempt to prevent folks from spinning up many new accounts to get these deals.
What would anyone use an app to order food from McDonald's? Just walk into the restaurant, pay cash, and walk out with the food.

I recall a year or so ago, there's been a story about someone hacking McDonalds loyalty program, with that app doing something stupid like storing your balance on the client or something. It seems instead of firing whatever offshore sweatshop that made that, they just doubled down on "mitigations".
