I’m sure they do, but they wouldn’t have introduced the pop up if people weren’t confused and complaining.
Right.
But they also introduced the change in the first place because people were confused. (Namely, it isn't intuitive to people that Apple Watch, AirPods, Continuity, etc. rely on Wi-Fi and/or Bluetooth. So they'd turn that off when they felt they didn't need it, then called support because stuff stopped working.)
The Control Center’s whole purpose when it was introduced was quick access to key functions. This goes against that ethos.
Not at all. You still have access to disconnecting.
There are other functions Control Center is missing that it could give quick access to, such as toggling VPN. Just because your and my pet feature is missing in Control Center doesn't mean Control Center is worthless.
More people would want to switch Bluetooth and WiFi off from the toggles rather than temporarily disconnect.
Again, I'm sure Apple has more reliable numbers on what "more people" want to do than some random MacRumors user does.
