Apple made over $10B from US App Store commissions last year

One thing I really like about the current App Store setup is I get a new phone and sign in with my Apple ID and all of my purchases are there for download. I don’t have to worry about buying it again or trying to find that one app I use every once in a while. I’m not sure how this would work with multiple app stores. I assume the other app stores aren’t installed through the Apple App Store? Are they? If not, do I have to remember all the app stores I’ve installed from. Will they be as great as honoring all my past purchases? Since I have no experience with this, just wondering how seamless it will be compared to the current experience?

I suspect with the recent court ruling allowing non-apple payments, you’re about to see this number plummet.
