It's probably not a great idea to point at a monopoly, as a defense of one's own monopoly, and claim "Yeah, but he did it worse." Both Google and Apple's platforms need to be cracked open to competition.

Android is already more open than iOS; you can already install third-party app stores, where the only hoop you have to jump is agreeing to a warning about installing things from "unknown sources". But yeah, Google doesn't allow rival app stores to be distributed through the Play Store, nor…
But on Android, you do have a market for app stores - there is Google, and then there are various bit players (F-Droid, Samsung Store, Amazon Store, and others). And Google is by far the biggest, and using their position to set the rules for all the others, including actively hostile actions like de-listing some apps if they don't offer exclusivity to Google Play, disallowing Google Play installation if the OEM doesn't ship it by default, etc.
