> The blocker is black and white stripes
On my ThinkPad it’s instead painted with a red dot. Because, obviously, the conventional meaning of a red dot appearing on a camera is “not recording”.
Not just the weird meaning, but on my last Thinkpad the red dot and the slightly red glean of the camera lens look surprisingly like each other. Even worse I managed to get the cover in a position where it looked like it was closed, but the camera could still see.
