The original response was about the likelihood of companies passing along savings to consumers. I cited manufacturing because it's an example of a company saving costs without passing along savings to consumers. Manufactured items are what people buy in retail, correct? So how is citing the retail store offering its own credit card changing anything about the dynamic per the manufactured retail goods?
IMO, all the stuff about payment processing has little or nothing to do with consumers or the prices they pay. The ACM itself doesn't even make a consumer oriented argument in its ruling.
Also, the ACM appears to be deliberately ignoring that smartphones have internet access.
"Various dating services exist on the Dutch market, which offer their services through apps. Since most consumers own an Android-based smartphone or an iPhone, most dating apps use the Google Play Store and Apple’s App Store. In order to maximize their reach, dating apps must therefore be available in both of these stores. After all, consumers also wish to reach other consumers with different types of smartphones.
On iPhones, dating apps can only be offered through the App Store, which makes dating-app providers highly dependent on Apple. Dating-app providers thus have little choice but to accept Apple’s conditions. ACM therefore establishes that Apple has a dominant position."
The ACM has ordered Apple to adjust the unreasonable conditions in its App Store that apply to dating-app providers. The District Court of Rotterdam has partially suspended the order subject to periodic penalty payments that ACM had imposed on Apple.

Wouldn't Android/iPhones both have access to the internet? Yes. Does Tinder have a web site version of it's service? Yes. So it's not actually correct for the ACM to claim that Android/iPhone users of Tinder have to rely on app stores.
