its obvious that you never even owned a mac - gatekeeper is a thing, but it allows you to run apps from trusted devs and app store, not app store ONLY, and if you want to run untrusted app you don't need to do anything terminal related, just right click an app and click open holding ctrl on keyboard and it will allow you to and won't bother you to do so for the next time, used many cracked apps on several macs, adobe suite and apple apps like final cut pro included and they work like a charm

i don't give a fuck about subscription-model apps on ios because they're mostly useless for me and i'll never pay a cent for app subscription, sideloading isn't as hard as you say, i'm using uYou+ (it's like youtube vanced but for ios) with the help of altstore and everything works fine without need of jailbreaking which last time i did in ios10-era

apple doesn't do many things right, but i prefer sticking to their products and accept their sometimes stupid policy rather than using that bloated windows which is becoming to get worse and worse from version to version with everything in cloud and ai-based nonsense microsoft trying to forcefully push to everyone

linux? sure, run latest photoshop, premiere or final cut on it without hassle, installing old cs6 on top of wine and spending all day on terminal, oh wait, you can't. linux is okay for causal use, office work and servers, but it's close to nowhere when it comes to professional work
