Apple isn't the best, no one deserves "best" in desktop and mobile operating systems, but it's the least bad.
In mobiles we basically have a duopoly, and the only ones who are likely to care about the customer's interests are regulators. Neither Apple nor Google have any incentive because there is no 3rd option.
Uh. Apple and Google compete with each other. Why would they need a 3rd option for incentive?
If there were 1-2-3 more options, that would give them incentives to be less shit overall.
MacOS and iOS are the most limited in terms of customizability (personalization) and freedom for developing software for them. As much as that might surprise you, many people care about that and can't stand to use Apple operating systems because of it.
Already messed up. Shouldn't buy things you don't approve of.
Namely: unrestricted access for new, small entrants. Less restrictions on utilities. Stuff like that.
My favourite pet example: I want DaisyDisk for iOS. What does Cook need threatening with to allow that?
On the other hand, Apple not allowing apps not approved by them and not allowing manual single app installs without going through their app store or some other app store does look to me like a monopoly issue.
Sounds like you just want the iPhone hardware, but not the spirit of the OS that contributed to what it is. Adding manual disk management makes more like running Windows XP than a smooth "mostly just works" phone.
But... "Other" ?
