Uber Eats opaquely inflates the base price of the food so that even when they advertise a low (or zero if you've paid for 'Uber One' to give you zero delivery fees on 'eligible' deliveries, whatever that means) delivery fee, you're still getting charged significantly more compared to picking up the food yourself. Call me crazy, but I would expect the delivery fee to be the difference between the cost to have something delivered and the cost to buy it outright.
Gacha games are famously deceptive and exploitative.
Airbnb has a good justification for keeping the location private, but it's typically pretty hard to get an idea of the value you're getting for your dollar until you actually arrive on site and discover just how functional the HVAC/kitchen actually are and how good the location actually is.
While you might not classify any of the three as "scams", they're certainly classic 'low-rent' advertisements for things that take advantage of information asymmetry to convince customers to pay more than they would be necessarily willing to if what their money got them was actually clear.
