I'm sorry, what smacks of fascism? The choice, in this case, is Apple's, inflicted on all of its customers. If anything that is not obviously harmful can be reduced to mere "preference" then what is the point of hiring designers? just deliver raw html code and a textfield for users to write in their own css, right? Of course, I admit this is reducing the argument to absurdity, but so is calling my position "fascism".…
Some people argue that Apple limits the users by not giving them enough options. You are of the opinion that Apple provides entirely too many user options. Not only should the users always have scroll bars on, but they also should not have the ability to turn them off. (correct me if I misunderstood)
1. this, and other "preferences" are not arbitrary or meaningless. They have real consequences (even if the only real consequence is minor annoyance)
2. the presentation of too many choices is in fact, a real and well documented anti-pattern in UI-design. Too many choices is cognitive overload. Programmers like choices. programmers like power. but ordinary mortals don't care what colour their window title bars are, as long as the colour doesn't get in the way of their job.
3. Given the above, it is the UI designer's responsibility to be very opinionated about what the defaults of a system should be, and what should be configurable as a choice. (the fewer choices the better, generally, from a design perspective.)
4. as a corollary to that, I am aware that "some people" are uncomfortable about Apple's lack of configuration options. Those people are not designers, and should not ever be put in the position of designing a UI. Or you end up with a monstrosity like the desktop linux ecosystem. It's essentially an argument from ignorance of the research.
