Honestly, a same-circuit "camera on" light is my preferred solution to this whole question, and I'd be happy to see the mic get a separate light or be tied into the camera circuit. The problem is that this doesn't help if you have a desktop machine, but you are not literally sitting behind it to notice the light. Software could still eavesdrop on conversations during that time. The nice thing about Micro Snitch is that it also keeps a log. Ideally, we would of course have all these levels of protection: a light, a physical switch to disconnect the camera and mic, sandboxing with camera/mic permissions, and logs like those provided by Micro Snitch.
