Tough luck my friend. I mean only because you want something unreasonable doesn't make it a right.
Example:
What if I want to buy the engine of a Ferrari but not pay the price for a Ferrari and just have it inside a Volkswagen?
The answer to that is also tough luck. You want a Ferrari engine, well it only comes in a bloody Ferrari so either buy the whole thing and then mod it yourself or tough luck. Same for Apple hardware. If you want just want one piece then you'll have to buy the whole thing and mod it yourself.
Nothing in this world gives you a right to have all your wishes fulfilled by others.
My point is that a car is a complete piece of hardware, all of which is necessary for it to fulfil its purpose, while computers have the advantage (over other machines) to be easily modified by software.
You are correct that my wishes should not affect others, but what about the wishes/needs of multiple people? Even if it's just a wish/personal preference, and not a fundamental property of software, should people's opinion affect private corporations directly?
All of this assuming that there are multiple people who agree with the notion of software freedom.
If people in your neighbourhood wish and need that you mown their lawn regularly for free, would you be happy to consider it? After all, it's multiple people's preference!
Could you please show me such an advertisement? I do not really follow Apple, and have failed to encounter it.
Further, what if I'm a user, who wants to purchase the hardware (and even operating system), but does not want the added security. Mind you that Apple has their own CPU and OS which is unlike anything in the competition. Don't I also buy the product for those benefits, and don't I have a right as a consumer to opt out of arbitrary limitations that I have no option but accepting?
