Good catch. Never used Remote Assistance, so I don’t know how different it is, and if it actually requires telemetry.
Although the broader issue isn’t the why, it’s that it does those things at all without clearly communicating them to the user. Even their documentation has severe lack of any kind of explanation.
The first few days, yes, but there’s nothing better than blank keycaps when it comes to learning how to type without looking at the keyboard all the time.
It’s adapt or die, basically.
