Fitt's Law is a factor, BUT I think the always-on-top menu bar made more sense when smaller screens were the norm. With a 4K monitor at the highest-possible resolution, it can take a loooong time to get the cursor all the way up there from the window I have tucked on the lower half of the screen. I'm not saying you're right, but you're less wrong than you would have been when low-resolution monitors were the norm. That is, when Fitt's Law was developed.
