If you’re worried about that only stick to downloading apps from the App Store. It’ll still be there but everyone who feels comfortable downloading apps from the entire internet also has that option now. Just like on a Mac or PC. You download anything there from adobe or whatever site you need an piece of software from. But the App Store also has content. It’s just now if I want to download something that apple refuses to allow on the App Store like ad blockers or whatever it may be that’s an option too. Some people might download something wrong but mac has done a pretty good job of not only making that difficult with checks but they also have malware protection
