I would consider it a non-standard usage of "low cost" to apply it to case of something that provides an important function for 1/1000th of the cost of the product. In any case, I don't think that's relevant to my point: I specifically said "important for laptops to permit a physical slider to block the integrated camera". That phrasing was deliberate: you don't want to trust the OEM's slider in the first place, just be able to add you own. So, am I addressing a strawman? What OEM impedes you from adding a slider? Well, actually, Apple says it's not recommended to use a webcam cover because of how they designed it. That is poor design and security practice. https://news.ycombinator.com/item?id=23795163 https://news.ycombinator.com/item?id=23795163
