Nintendo don't have a standard desktop form-factor system either. Nor does BMW, Canon, Panasonic, or the Raspberry Pi foundation. They all seem to be doing reasonably OK in their respective fields without one. What is your point?
PS: *Every* major company treats its customers like sheep. In fact, to be fair, compared to some (Google, Facebook, et al), Apple does actually seem to do it a wee tiny bit less; *you're* not the 'product' at Apple.
PS: 'Time', as well as 'skill', is an important commodity. Not everyone wants to use it to (learn to) build their own machines, mine their own copper or extract their own teeth. Sure, some do, and that's great - but that's for them. I don't make my dentist feel crap about not being able to install a network switch. This whole "Well, I do this, so it must be right for everyone" crap needs to cease. Reasons.
