You've made some statements there but provided no context. Why is it a bad thing? I've been on the platform since 2007 - the App Store has been around since 2008. To date, I have had exactly 0 issues. Annecdata for sure, but I'm clearly not the only one to have this experience.

I feel I could flip the question around, why is it a bad thing that users can use other sources to retrieve and download apps? This is already the default line of thinking with a PC.

Most people will not be taking advantage of this option; many won't download outside the IOS store, and many companies won't make a new storefront to get around 30%. because hosting a storefront is expensive. Fortnite took themselves off Google play and they likely lost a lot of sales. But that's on them to decide.

Why is it a bad thing to give a dev a choice of hosting powers? If you don't, they find loopholes that inconvenience the user regardless. e.g. you cannot sign up for Spotify or Netflix through your IOS device.
