I was going to say the same thing: somebody gave me a fancy-ass business card on really nice cardboard which is thick enough to block everything perfectly, but fancily plasticized in a way that half of it folded beautifully into just the right shape to fit on the top edge of the lid/screen section perfectly, so that it almost looks like a purpose-made cam cover. And if I want to use the cam, I just slide it to the side, and no worry about adhesives causing problems (some plastic thing along those lines would actually make more sense to me as a purpose-made store-bought cam cover than the things in the article, frankly).
(Luckily, I don’t need to worry about the mic, as my laptop doesn’t have a built-in one, just a jack, so all I have to do is not plug it in.)
