> It's also a bit weird to see a service advertise their price discrimination.
I think there are two angles here that are can be rational depending on what you are selling, and to whom.
One is "stakeholder consumerism" similar to e.g. fair trade coffee. Some consumers want their payment to be part of a system that shares benefits with other parts of the economy. The provider is saying to the rich world, who will provide most revenue: you pay more so that I can provide my service everywhere while maintaining some margin.
The other is reassuring people that your price discrimination "isn't personal". All prices must thread the needle of making the product more valuable than the buyer's next best alternative, but the alternatives vary from buyer to buyer. PPP isn't perfect but it's a non crazy proxy for what the buyer is giving up to have your product (eg one dinner in Switzerland vs a month's food in Cambodia). And yes, it's a weak proxy when one region has a really wide range of incomes.
