The wealthiest person who I know well would absolutely fiddle with an app for 5 minutes to save 30 cents on a sandwich at McDonald's. He's cheap AF.

But even if he weren't that way, making the app deliberately bad to eek a few more clams out of a subset of people is perverse. Deliberately erecting barriers between the products and those who want to buy them is not how business is successfully done at this level. They aren't selling Ferraris here.

"I want to stick it to these rich guys, so I'll make the app terrible!" doesn't make sense. They're neither smart enough to do that, nor dumb enough.

The simplest explanation is that in a world of shitty software, this software is also just shit. :)
