The Fahrenheit 451 analogy sort of falls apart though when they give open access to the internet via Safari. What Apple does with the App Store is maintain a safe & friendly environment for users, where they can trust they won't run into things like viruses or pornography.

This creates a positive feedback loop when better sellers gravitate towards curated platforms first.
At the end of the day, plenty of people are still going to buy Android phones because a large majority of buyers buy on price, not on the quality of their platform's app ecosystem or whatever. This argument of not being able to side load apps, despite not being true, is one you'll often run across in people trying to avoid admitting that they really bought based on the price of their device. Hey I mean, it's their money, who am I to say they made a right or wrong decision with it? But just be honest about it.
The app sandbox argument is a better one, because it's actually true. But it's a matter of whether you think app sandboxing is a good or a bad thing.
