I’m all for breaking up Apple’s control on what I can do with my device.
Do whatever you want with your device, no one is stopping you. What you (and Epic) are demanding is more than that, you are demanding that Apple HELP you do whatever you want with your device even if they’d rather spend their time and resources elsewhere. Additionally you are saying “I don’t care if there are advantages to Apples approach or if some people prefer it, I want it MY way and that’s the ONLY way that should be allowed!”
I mean this question in good faith: for the folks who are worried this would affect the security of your device, can’t you not download apps from a third party store? Outside of that, what are the reasons for defending Apple?
It’s not as simple as “just don’t use it”. Changing the OS to allow it AT ALL opens up security holes. Apple would have to devote significant resources to the following:
1. modifying iOS to support side loading
2. Modifying the security model to deal with the increased attack surface
3. Handling and responding to more security threats due to the increased attack surface
4. Dealing with customers who screw up their devices due to side loading
All of those things cost people and money and time. All of which could be spent elsewhere instead. Why should Apple be compelled to do something they don’t want to do and many of their customers aren’t interested in just to placate a small number of people who do want it but are too entitled to just buy an Android phone that lets them do all that anyway?
Aside from that aspect of of it there is not wanting to reward Epics disingenuous and self serving behavior.
There is not wanting to set the precedent that eliminates companies like Apple from offering a choice in the kind of devices we can buy.
There is not wanting to reward the people who can’t seem to tell the difference between “I would prefer if Apple did this or that thing different” and “Apple must give me what I want or be forced to!”
I’m sure others have more reasons, but there is a few to get you started.
