Sadly about 98% of real world users are going to fall into scams, ransomwares and stuff. They are not mentally challenged, there are just so many traps/fakes/tempting stuff that we as IT people are more aware of (but even we still fall into some).
We also can't count on every person being able to check every single thing they do: how do you check if some food or drug you get is good or not? you can't really, you have to trust someone who knows.
It’s a bit like the Elizabeth Warren toaster analogy. If you bought a toaster with shoddy wiring and it caught fire and burned down your house, everyone would blame the manufacturer and not sneer at you online for not learning electrical engineering and not checking the wiring yourself before using it.
It's more like if I buy a reliable toaster, but I buy bread that's secretly poisoned by the manufacturer and hurt myself. I'm not gonna demand the toaster maker add a poison sensor to the toaster and say "how dare they didn't protect me!"
I don't buy this in the first place. It is reasonable to expect consumers to do some background research into the products they buy. In fact, it is the only way capitalism can function as a meritocracy.
Society should be more dangerous as a means to force people to learn more about technology they rely on.
I'm not sure what you think is so harmonious about it. I think there are gobs of iPhone users that wanted a free store, created Cydia, had it shut down, and have been fighting ever since with tools like AltStore to try to restore their own ability to install software of their choosing on their phones. Simply searching any search engine for "build and install iOS apps locally" results in gobs of discussions where people are trying to figure out how to actually get control back of their device and work around all of Apple's restrictions.
Further, the state of affairs has steadily gotten worse over the years as Apple tightens their restrictions, adds more barriers to running apps of your choosing, and having agency over what programs you can actually run.
This is a war on general purpose computing. And sure, there are gobs of people who don't care, but there are many who do, and they're fighting for the rights of all of us. My own mother-in-law who spent thousands of dollars on Kindle books didn't understand that she couldn't ever read any of those books using anything other than Kindle, and that she could never give them to somebody else to read (like my son who doesn't have an Amazon account). These people making these decisions are not well-informed. They assume they're not being screwed over, but they're in for a rude awakening.
We are rapidly moving to a world where there are no options for people to run software of their choosing on mobile devices. And we already know that the mobile manufacturers operate at the behest of the US government. This is not a pattern that I think is going to serve us well in the coming decades.
At some point, you have to figure out who your mobile devices are working for.
