I get what your saying, that the personal risk is low, especially compared with say driving or heart disease. Heck, I'm a middle aged heavy guy and couldn't care less who sees my nudes.

But, I believe we (as technologists) have a responsibility to use and push for strong security practices. I don't want my kids to grow up in a world where creeps blackmailing them through their webcams is a possibility, or where a rogue politician has all the tools of absolute authoritarianism already set up and waiting for him.

A camera cover is a huge win. It's super easy and cheap (a piece of plastic), it's easy to understand (entirely mechanical), it works 100% when used, and it's failure modes are obvious. Not all security controls are cheap, easy, and 100% effective, but this one is. And if you don't bother to use it in your bedroom, then that's fine, but every webcam should have one.
