Why not cover your camera? Some MacBooks are so delicate that Apple itself warns stickers can break them IIRC¹, but to me that’s just one more great reason never to buy a MacBook. For other cameras, if someone can look into my windows, they can also watch a lock-picking video on YouTube and IIRC learn that something like ≥70% of American homes have locks from the same 1–2 brands, and break in easily, but I still close curtains, because why not?
