Or you could just not give them admin rights and create limiter users for them. You do not have to surrender super-admin right to corporate overlords to solve this problem.
You want to limit what current and future generations of people can do with their computers because of something a computer illiterate grandma may have done in the 90s?
You badly overestimate both the ability and interest of average people in learning to administrate their computers. They just want to get shit done and go do something else. Computers are a tool at best, and more often a super-annoying thing they have to deal with but hate every second of it.
If they actually like any of the computers around them, it's probably the most locked-down ones: their phones and video game consoles.
[EDIT] That is, you're way off in thinking it's only a bunch of soon-to-be-dead grandmas who have trouble operating computers that don't prevent them from fucking things up too badly. The "digital native" generations are barely better.
You can have a locked down mode. You can even sell it turned on by default. But to exclusively prevent everyone from using their computers as they see fit because you think some people are too stupid to handle it? I don't believe you actually want that. I believe that's an excuse to ensure Apple gets a cut of everything that happens on their soon to be landfill machines.
I have almost zero interest in haxoring my phone, and just want it to always work and not let 3rd parties steal my info, automatically.
And I'm a life-long computer geek who's done professional mobile development. Most people care even less than I do. They just want it to work, because computers aren't their life, they just use them to get stuff done, or when someone else tells them they have to. Would it be sort of nice to have the option to unlock it? Yes, exclusively so I could run pirated games in emulators more easily, which is the only thing non-programmers I know with unlocked Android phones use all that freedom of theirs for. For most people, they'd not pay even a couple dollars to have the unlock option. It's worth basically nothing to them, because they do not have any actual use for it. But sure, it'd be nice. It's just not a big deal.
> If yes, man that's really dangerous thinking.
The NES had a DRM chip—a bad one, but still.
Some computers have been appliances, and some have been programmers' machines, for a long time, and the sky hasn't fallen. The former have just eaten some of the use cases for the latter, where a fully-capable general-purpose computer was at least as much of a liability as a boon.
Even Apple still makes normal-ass computers for people who need them. If your reaction to that statement is "pft, yeah, but they're clearly trying to get rid of those", well, people have been saying that for more than a decade, and it still hasn't happened and doesn't seem to be any closer, so... I'll believe it when I see it.
For one, being able to use your computer/phone like a computer isn't 'haxoring'. Jesus. And second, Apple _lets you_ now (mostly anyways), because people with sense still raise a stink. So, basically, you're welcome. Stop screwing it up for the rest of us.
Consoles play games and media, off course people like them. Did the PS3 having the Other OS feature mean people enjoyed gaming on it less? I don't think so. Piracy as the given reason to take the feature away is a poor one, they could've better isolated the gaming partition. Apple designs their products to be more user friendly than most, it shouldn't stop users from doing what they want. They don't on the Mac, but they do on the iPhone.
