This seems to be overstating Apple’s position as neutral here, they are actively hostile to jailbreakers, and Apple will try to stop you any way they can.
Why is it important? Because when described incorrectly, solutions will also be incorrect. Apple doesn’t control it because Tim Cook gets hard when doesn’t allow some apps into the phones of the customers. They do it because they want to be paid for the intellectual properties and opportunities they provide, they also want to be able to continue selling iPhones at premium prices and in this competitive environment they want to be able to control the working of the devices so to provide premium experience.
Well too fucking bad. They can offer their premium services as a fair competitor in the market and if people want that, they can choose it, and if they don't, they can choose other things.
Yes, that's exactly the situation. If people don't like it, they go buy a Samsung, a Pixel, Xiaomi, a Huawei, a Sony etc. There's no need for Apple be compelled do anything, there are plenty of options when you don't like the Apple offerings.
And those alternatives are not like Bing to Google, these are very viable alternatives where Apple is actually a small minority of the market. It's %50 in the US and much, much less in the rest of the world.
Every major cosumer 'computer' in history has allowed this as far as I can tell. Yet for some reason now in the last few years its unthinkable on specifically Apple devices. I'm sure it's merely a coincidence they make billions of dollars off of this overly draconian "security" framework.
At the software layer? It's been litigated on more than one occasion that a company can't sue people to prevent jailbreaking their own devices.
