I've seen HP desktops that have a closeable camera cover, and Lenovo does on some ThinkPads [1], so probably others do too. Laptops usually have very little depth available in the screen part though, which is why most laptop cameras are crappy (exceptions include Surface Pro and Surface Book, which have more depth available and so much better cameras than most, but no cover - at least their camera light is not software controlled).

I have a sticky piece of post it note more or less permanently affixed over my camera.

I can remember when someone spotted tape over Zuckerberg's laptop camera. Ref: https://www.theverge.com/2016/6/21/11995032/mark-zuckerberg-...

I had a closable cover and someone shut my laptop with enough force that the cover caused the screen to break. Be careful when closing.

Sure, that is going.to be true for anything with moving pats. Yet I would also imagine that design and materials are a factor here. Let's face it, these covers aren't exactly common on laptops. There is probably a lack of good design practices for them.

Was it a built-in camera cover, or a third-party one? Apple specifically (and possibly other manufacturers?) recommends against third-party covers because the tolerance is so close:

My Thinkpad does.

I also purchased a cover for mine, although in a pinch, the removable stickers on fruit work well.

Higher end Lenovos and Dell Latitude / Precision tend to. Was one reason why I went for a Latitude 74XX rather than a 54XX or 34XX when looking at them last time.
