This is ugly. User behavior modification as a product goal. The reverse of how you should build products. You need to start with "The user wants to do X." rather than "I want the user to do X." Who is Apple to dictate the "correct" way for me to use a mouse?
Users aren't designers, they don't know what they want and will put up with bad experiences because they don't know it can be better. If Apple let the mouse be used when plugged in, everyone would do it immediately and never try using it unplugged cause of their battery anxiety from every other device. Then you try it unplugged and you realized you have to plug it in for like an hour every couple months and it's way…
First, I definitely know what I want from my computer.
Second, flipping my mouse over and being forced to stop using it is an objectively worse experience than plugging it in for charging while using.
I have an MX Master 3 which is also wireless and charges with a cord. While it's charging, I definitely have a degraded experience relative to the wireless one, so I unplug as soon as I can (I sometimes don't even wait for the full charge!) to go back to the better experience. Never once have I considered keeping it connected indefinitely.
