Earlier quoted context omitted.
I am convinced they were ordered at some point to include cameras. They definitely drive up the cost of laptops, especially earlier on when webcams were more expensive. There were so few practical uses in the early days and so few people actually use them today that I am surprised few laptop manufacturers don't allow for security.
Few people use them? I really doubt that, especially with so many people working from home these days.
Additional of all the people I know - friends, family, parents, children, etc., only one of those people use the camera on their laptop. Some use facetime on their phone. But even for the mac users, it's a complete rarity.
