100x this - and Hacker News is really guilty of doing this.
How about we focus on making understanding the risks more accessible to users if we think there's a legitimate problem with users "not knowing what's good for them"?
Is requiring certified electrical wiring that much different from a “walled garden”? Some people tinker at the edges of their home setup, but you’d probably be pretty worried if you found out your average neighbor had rewired their whole house on their own following some lifehack they found online. Computers are connected in a different way than neighboring houses, but it doesn’t mean you aren’t affected by the decisions of your digitally-close acquaintances (from worms and botnets down to simple email/contact harvesting).
That’s not to say the world hasn’t benefitted greatly from software choosing velocity over robustness; other technologies have followed similar early arcs, causing damage before they matured. Maybe we’re at the point where limiting choice is simply one of our least-bad strategies for most people? For what it’s worth, I am pretty confident that the vast majority of people want computing appliances and not tools (why would computers be any different from any other consumer good?), so I find it highly unlikely that the pro-tinkering arguments apply outside of a tiny proportion of users. I definitely don’t mean to imply that this is the only way, but it seems like there’s already a spectrum of choices for consumers and sometimes it feels like we’re arguing to narrow the less “open” end of that spectrum because we’re projecting ourselves onto the whole population.
Yes it is very different, because those certifications are limited to basic safety whereas Apple's restrictions are a wild mix of security protections, paternalism (e.g the porn ban), protecting their business model, and staying in the good graces of authoritarian regimes.
If Apple really cares about security they should not blur the lines between security and unrelated issues.
I don't believe that typical end users are knowledgable enough about computers to know that they can or should ask for this in the first place.
Anecdotal example: My computer illiterate mother wants to download some random unscrupulous DMG onto her Mac, claiming to be a file conversion app. I catch her in the act, and tell her no, don't do download that.
Now did my mother ever ask to be prevented from doing this? No. Does she even understand why me preventing her from doing this was a good thing? No. But was it in her best interests overall? Yes. I view the gatekeeping functionality of iOS as largely replicating my role in this scenario.
