Why is a devices MAC address important enough to cause operating systems like Apple and android to spoof or hide a MAC address when not connected to WiFi? Why is a big deal for another device to see your actual MAC address?

The issue with a static MAC address is that it could be used as an identifier to detect/log the presence of a specific device. By extension, it could in theory to be used to detect/log the presence of a specific person known to be in possession of that device.
Since it’s easy enough to randomize it in specific cases, there’s little reason not to unless it breaks compatibility with a specific usage scenario.
