My interpretation of the article is that it wasn’t Google’s app store but the deals Google did with other manufacturers and big studios that caused them problems. Unlike iOS Android has both open source and commercial forks. Amazon have their own app store for their own range of devices and you can load that app store on regular Android I believe if you want to access a shittier range of apps. There are degoogled versions of Android and many people including myself run f-droid or side load apks. It is much more open than Apple’s system which won.
