Price discrimination is basically corporate speak for giving discounts to those who wouldn’t or couldn’t afford to pay full price.

And it makes perfect sense in this context - if you make $200k salary you probably don’t care enough about a $0.30 discount to fiddle with an app for 5 minutes. But if you’re living on a few dollars of food budget, you probably care a lot about that 30 cents and would fight for it. So making the app bad allows them to segment the market to get an extra 30 cents out of the person who can afford it without excluding the low-budget person.

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. :)
