So what? Controlling how many fart apps are available on its platform does not make Apple a gatekeeper to any part of the Internet. Apple does not funnel Web traffic into its properties.
Think it through: Amazon dominates shopping-search results. It easily swamps any other shopping portal or indie vendor. So it is a de facto gatekeeper to a huge portion of online shopping. You're citing Apple's alleged 58% of phone-platform share as making it a gatekeeper to the Internet? Amazon is actually an Internet-based entity with huge dominance in its field.
Meanwhile Meta (Facebook) IS the Internet for a large (less tech-savvy) portion of the public. Akin to when AOL slapped Internet access onto its platform.
Apple controls its app store. Is it douchey as hell to developers? Yep. Has it antagonized governments and flouted legal rulings? Yep. Has it lied about App Store search? Yep.
But it is not an Internet gatekeeper or a monopoly.
