Take a look at history on how Epic is handling their store on the PC space. There will be exclusives. Also if you think apps like Facebook will remain you are not involved with how these companies operate. They will leave so they don’t need to disclose what they track.
Right so don't download them then? No one is making you keep these apps on your phone. Play another game get another social media app. Tell Apple to make better apps if you want to be locked into the app store. Or make your own apps.
I don't get why people think developers should have to cater to them. Epic should need to pay 30% of their transactions to Apple just because you want it that way and don't want to sideload? Nonsense. If they want to lose customers that way it should be there choice. Not Apples.
