Would you say to someone, “Wow, you must hate dogs. You only have one. You enjoy his company and playing with him, but seriously, only one? What do you have against dogs?”.
No, you wouldn’t say that. Because it’s a stupid thing to say.
The shallow assumption of Apple’s buttons is they hate buttons, the deeper conclusion is they love the shit out of a few important buttons. I bet they obsess over the placement, color, label, push-back and feel of every single button on every Apple device.
