Ah oh, the "security" power word has been brought up, time to turn off our brains and accept everything i guess :-(

No, seriously, how would you build a computer platform that everybody, even computer iliterate people can use and install programs without constantly ending up with malware, scams and other nasty stuff that steals their money or information?

The apple iOS model seems to be the most promising here. It comes with huge tradeoffs in user control but for a large part of the worlds population I think its the right choice.

You should try a linux system. They have an app store equivalent, but where everything is safe (as in security).

But in this case you dont lose any level of control, since the appstore itself there isnt limited. The only thing not allowed is unsecure apps. Thats all.

Yes the iOS idea is great, but there is no need to impose arbitrary restrictions.

You can have a kiosk mode in any OS without giving up freedoms for people who don't need to be straight jacketed. I don't want to beg Apple or Samsung or Google or Microsoft or anyone for the ability to program a computer that I purchased.

I think what you describe is really overblown - i know many computer illiterate people and 99% of the issues they have with their PCs is about what will happen if they Like something on Facebook or Microsoft forcing some update that takes ages to finish in their $250 laptop. The same people also run Android (which allows 3rd party installations) and they never had any issues with malware - largely because they never install anything outside the Play Store (something that explicitly requires turning on an option in settings that they have no idea about anyway). That would work with iOS perfectly fine.

As for the PC, i think what Apple was doing with macOS until recently (allowing you to run unsigned software you downloaded from the Internet by doing the "right click dance") was a perfectly fine compromise between security for computer illiterate people and still being in control for people who know what they are doing.

Nothing about Apple's model requires Apple to be the only one who can say what you can do with your own device - you can still have Apple be in control by default but also provide a way to take control yourself if you know what you are doing.

Then make it hard, with a scary pop up, so technical people can make an informed choice and tech illiterates cannot.

Pop up theatre seems to stop very few non-technical users from clicking allow. This is why so many people get their family iPhones to start with.

Were technical people informed that installing Fortnite outside of Google Play made their phones vulnerable?

or get a package manager equivalent like linux systems, that solves literally all these issues

Security isn't that important.
