I recognize this may be a very autistic answer (i am)

The function of a button is to be pressed, to put functionality on the bottom of a stationary device feels incredibly wrong. Thats really all there is to it.

I can forgive a reset button being on the bottom because ideally they aren’t ever pressed and you definitely don't want them accidentally pressed. I recognize that for macos a restart is usually a reset troubleshooting step and i would be probably be fine with it the button was renamed with an explanation on its actual usecase scenario.

In any regards i feel like it makes much more sense on the back where the cables go in.

I have nothing against apple besides the general capitalist/consumerism stuff. I hate google and meta much more.
