This only applies to those applications whose role is to generate revenue directly (B2C), and in a specific market segment or region (high income and/or US/EU).

For other types of applications the need to service a wider audience can often trump this.

Think banking applications that are without any kinds of in-app purchasing or upfront cost of use.

Or state healthcare sponsored medical/health tech applications.

Or industrial applications that need to run on rugged devices.
