Yes there is. It is no longer up to the individual but up to the developers. Facebook will leave Apple's store. Maybe Office will. Maybe Affinity will. Maybe Adobe will. Epic will create their own store, and purchase up exclusives (proof: They are doing that on PC to "compete" with Steam, so to "compete" with Apple's store, there will be exclusives). Its now developers.Not sure if you are being sarcastic in your statement but even if this is permitted there is nothing stopping anyone to not use the official Apple AppStore.
And again, I keep repeating this yet NOBODY HEARS IT: Epic sued google for it being "too difficult to side load", so changes WILL come to Android too. All the people advocating this on this forum are NOT looking at the big picture. They just go "YAY I CAN EMULATE NOW!!!!".
What is SO EXTREMELY BROKEN with iOS that it is impacting the customers? Emulators? Porn apps? What? Tell me.
This is being driven by companies NOT people. Android will have changes too, things will be much worse. Let's stop it NOW before it's too late. Think more than 6-12 months down the road. Think long term, think of the ramifications.
I am tired of hearing the same thing over and over and over again that "we can keep it locked down, it changes nothing", it changes EVERYTHING. It's now under Epic, Meta, Microsoft, Adobe's control if I side load or not. And if you counter saying I can no longer use those apps, well you don't need to use emulators now too.
Nobody has answered if it can be 100% guaranteed that any and ALL iOS apps MUST 100% be offered in the Apple App Store too. Unless that is included in this law/regulation, then everything is going to change. The minute our favorite apps leave Apple's App Store, we need to side-load.
NOTE: Emulators is the most common discussion point in these conversations. If you don't care about emulators, take it as a generality.
