Well if you have the Find My Device functionality enabled, not being able to turn off Bluetooth (and WiFi) is a good thing, since a thief cannot disable location deriving and reporting features by turning them off.
I don’t think those are connected…or at least it would be silly for that to be the case. Say your laptop was stolen when your BT was off for some random reason - does that mean you won’t be able to find it?
Yes but does it matter if your BT is turned off _visually_? The device can still send data.
Besides, receiving consumes more power than sending, theoretically Apple can just shut off the receiving part and send intermittently (every 2 sec or so) and achieve very minimal power usage.
Again, this is just speculation, I’m genuinely interested in the details.
Whether other OSs do by default is irrelevant. Are you saying that I just be content with the ability to turn off WiFi?
Besides, MacOS is cherished by many as a UX/UI masterpiece, yet there are many annoyances that need to be fixed by the user. For example window management is a big one, I simply haven’t been able to achieve the comfort of i3 on my work Mac. (tmux comes close, but I can’t run Firefox in there)
