You lost the point too, this kind of systems are already used,
do you even know how you enable side loading n Android? or disable secure boot on a PC ? have you seen the warrnings that appear when you allow a webpage access to your webcam ?
Apple has designers that can create a UX that will stop 995 of idiots to enable a dangerous option without knowing what they are doing. You did not responded why is not apple protecting the laptop users from their own stupidity.
Here is the exact problem we are talking about, happening today on Android.
The mechanisms you are talking about have been proven not to work.
As for laptops - they are. It’s not ‘stupidity’ that causes most people not to understand these risks. It is a lack of time to develop the expertise. Many people would like to pay Apple to manage these risks for them. For those who do not, there is Android.
I prefer the risk of some people installing some bad apps then the risk of Trump forcing Apple or Google to brick my device that I own.
You are still avoiding to answer why is Apple not locking down the MacBooks ? I mean is for the users safety, are this users in danger and Apple not caring enough abut them?
The answer is simple, you can make it safe by default and let the user unlock their device(from BIOS or from a setting s) Apple can afford to hire a UX designer to make the warnings clear for average person, can afford a lawyer to put some disclaimers there, can afford some developer to implement this unlocks. The reason they do not do this is not for your safety is for money and when they will be forced to implement it I am sure you will praise them on how a nice job they did when implementing it.
If you prefer to take the risk, then you are free to buy an android phone. For those who don’t, they can choose an iPhone. That is the current situation, and it is good. Taking that choice away by force is not.
You are proposing to have the government start mandating software features, which is absurd given your claim not to want the government controlling your phone.
I already answered your question about your MacBook but you chose to ignore it. The answer is that they are locking down the MacBook to protect users.
As for the ‘hire a UI designer’ argument. That has been proven not to work, but again you are pretending not to see this.
They obviously wouldn’t be allowed to make it so difficult that nobody could be persuaded to do it, which defeats your point.
