Look, we're not saying anyone's watching you. We're not saying that some secret organization has taken over your webcam and is recording you, right now, as you read this sentence.
And we're definitely not saying the government's watching you. We're not saying that the FBIor the NSA took over your laptop's camera and are making sure you're not using your Onion Pi too much.
But let's just say, hypothetically, that it wasn't crazy and that someone did want to take over your webcam and watch your every move. And let's just say you didn't want them to - because you were building an open source cell phone jammer, or an Arduino anarchy inciter, or you can only do one pull-up and just ate a whole bag of Bugles.
Then maybe spending a couple bucks on a set of ten, high gloss webcam blocking stickers wouldn't seem so ridiculous. They're pitch black, like an eye-hole-free balaclava for your computer's built-in webcam, and have an inset, light black logo to rep your privacy concerns.
Again, we're not saying anyone's watching you. All we're saying is that they might be - and isn't that good enough?
