And misleading the other 95% into thinking WiFi/Bluetooth are off when they're still active.
Just another one of Apple's thought-less design implementations of late.
You're mistakenly believing that every user believes that button completely turns off wifi. As most simply want to disconnect from the current network and then have to take the additional action of turning wifi back on shortly after, the new implementation is what most user really want. If you want to turn it totally off, just take an extra 1 second to do so in the settings. Now people can have both.
But go ahead and cry about it. I'm sure that'll change things.
