We should have the ability to run any code we want on hardware we own

I want my less tech savvy family members to be able to buy locked-to-the-company-store hardware, that they can’t run other things on, as it protects them from one avenue of scams and hacks. This protection can and will be worked around if it can be easily disabled.

Fully open phone systems consistently fail to sell enough to make a difference, which is a bit of a shame, but honestly at this point the market has spoken.

You provided an alterative solution yourself. Make protection harder to disable, so non-tech savvy users can't disable it easily, always inform them of the consequences of disabling it and make it that it's only needed in exceptional cases (there a lot of room for improvement here).

If they want to climb over the protection fence, they should be able to do it as they clearly WANT to do it. Why should you have control what they can or cannot do? (Unless they are your kids.) Should experts in other fields also be able to control over what their layman family members are allowed to do?

> always inform them of the consequences

This would be about as useful as telling the cat why he can’t go out right now. The words would not be understood, as they won’t be by probably 90% of humanity.

> If they want to…

They don’t. Categorically. The only reason they would try is because they are being scammed with offers of getting something or cajolement entreating them to allow it.

> Why should you have control what they can or cannot do?

Me? I’m not asking for control. I’m saying that most people aren’t equipped to understand the threats they face, even in the face of explanation or warning, and their use-cases are comprehensively covered without it. My parents are old. My brother ends up with any PC he owns full of malware and viruses. The current status quo serves them and many millions of other people very well, and we need to be very cautious when arguing to rip this away in the name of our freedom - to them it only represents freedom to be exploited.

Experts in other fields determine the extent of what all laypeople may do legally all the time. Or do you live somewhere that there are zero restrictions on (for example) gas plumbing or work on electrical systems?

You are overblowing it out of proportions. Majority of people are capable of understanding warnings just fine, you're not that special. When they can't, it's usually because it was communicated poorly. More often, they choose to ignore it, because of too many useless and overblown warnings.

Why aren't your family members sending money to the Nigerian prince? I bet your parents and brother are able to perform money transfer, so the tech isn't blocking it, but they don't do it.

Windows has very poor security model. It fails all security requirements I mentioned in my previous post. Needing elevated permissions to move a shortcut to a subfolder on their desktop just trains users that a lot of warning in Windows are useless.

A lot of dangerous and stupid activities are legal. Experts influence laws, but they don't have the power to prohibit laymen around them from doing legal things. Running software of your choice on your devices is legal last time I checked.
