How irate would people be if a developer from Nairobi got their app update rejected because they couldn't find an Asian woman to pose for one of their screenshots for the App Store?
I agree that diversity is a good thing, but it's important to remember that not every developer can afford to hire models to show diversity that doesn't exist in their country.
Then we can have a screenshots as a service, where you send in a bunch of screen shots, and the SAAS returns a suitably diverse range of models holding devices with the screenshots showing.
It could even be generated with a neural network so that you don't need to find or pay models, and you can configure what physical disabilities they might have.
They could have a Screentime-type system just for being transparent about what you or your family spent in the last week on subscriptions, apps and in-app purchases, what free trials are ending, what apps have active subscriptions but no usage etc.
They could make virtual currencies show the real price if they were bought with real money. They could require 'free' transactions with virtual currencies to go through the same payment authentication.
They could make subscription apps require an ongoing service or value being added, aside from fixing their own bugs or trying to improve their software to attract new customers.
More interestingly, Apple, arrogating themselves to this role, is directly responsible for all the things that are not done, in that list and not in it.
As Tim Cook said it's not all about the bloody ROI.
For example, they could require that the models depicted in app store screenshots are visibly diverse in all locales.
They could require a certain level of screen reader or even color blindness affordances.
They could require that the ultimate beneficial owner (UBO) of the software be listed on the app store page.
Disclose which companies' telemetry software ships in the SDKs of the apps. List their UBOs.
Require apps to disclose their in-app marketing budget. I guarantee you this would correlate strongly negatively with app quality.
Many radical ideas.
