After having identified Chromium as the culprit, developer Ofer Zelig said in a blog post: “While I was working I thought ‘I’m noticing that an LED goes on and off, on the corner of my eyesight [webcam]’. And after a few times when it just seemed weird, I sat to watch for it and saw it happening. Every few seconds or so.”
Google also blamed the Linux distribution Debian for downloading the non-open source component with Chromium automatically, rather than Google Chrome.
“The key here is that Chromium is not a Google product. We do not directly distribute it, or make any guarantees with respect to compliance with various open source policies,” Google developer mgiuca said.
Falkvinge countered Google’s explanations saying: “The default install will still wiretap your room without your consent, unless you opt out, and more importantly, know that you need to opt out, which is nowhere a reasonable requirement.” He says a hardware switch to disable the microphone and camera built into most computers is needed.
