The mouse charging port is on purpose so you buy two mice. Apple sucks guys stop pretending they do much to benefit you. When you buy a new iMac it comes with one charging cable for two devices lol.
I thought it was to force people to use it as a wireless mouse and not just leave it plugged in all the time. Or so someone said. Still annoying but not really on the level of “we’re trying to force you to buy two”.
