Good news! You can still only use Apple's app store, and not worry about this supposed garbage that will be everywhere. Because Apple will still be curating and vetting all the apps in their store, you have nothing to worry about.
Also I doubt other stores are going to charge a subscription fee like streaming services do. So there's nothing wrong with having multiple stores.
You're mindlessly repeating Apple's bullshit.
That and their curation and vetting process turned into complete garbage over the last few years.
