Which is a good thing to happen, let the consumers decide where to buy Apps from.
I would go to Apple, others may have a different choice.
Nope it would be the worst thing possible.
It would mean that parental controls on budget use are gone (or do you think those selling berries at 1000$ a pop would care to implement self-control if they don't have to in order to be allowed on the app store?)
It would mean that we all have to use dozens of different stores as all the big ones would rather have their own store than to pay Apple or anybody else.
It would mean the small developers would lose out big time as the big developers leave the apple store and hence they won't get the economy of scale there is now that allows them to get everything they need for 99$ a year.
It would mean the Apple app store become less relevant as the big ones disappear rom it and it would hurt the small developers big time as the Apple app store becomes less relevant to users. I wish them good luck on finding another app store that's going to be as fair to the small devs as to the huge ones as Apple is today.
It would mean you need to upgrade apps from every possible app store every time. You'd have to track down which app store has what app today for yourself, ...
It would mean much more uncontrolled access to all the sensors on our phones and that will lead to much more massive privacy violations.
The moment Apple stops being the gatekeeper to my phone by allowing another app store on it, is the moment I sell my iPhone and buy the dumbest phone I can find instead.
Or maybe just uninstall every last 3rd party app on it till it needs replacement.
If I wanted an android device, I'd have bought one.
