These usually get neither an LED nor a switch, and unlike cameras can't easily be covered, nor pointed away from potentially sensitive topics/subjects.
For example, I'd not be happy having my voice auto-transcribed by some malware as I authenticate to my bank providing my SSN etc (which as an authentication method is of course horribly insecure, but that's a different discussion).
Of course, this will vary from person to person, but as mentioned above, just being able to mechanically cover a camera when required makes it less of an issue for me.
Also, getting a voice sample in the first place gets significantly easier that way: Not everybody publishes video or audio recordings of themselves online.
Lots of ThinkPads have «Microphone is muted» LED. Not exactly what's requested (and is bound to a software mute/unmute shortcut), but it's better than nothing regarding state of machine being observable with a quick glance.
Which reminds me, to strengthen your point, it doesn't have 100% keystroke recognition, but there are works[1] on keylogging via audio, and 93% via Zoom-quality audio streams is concerning enough for me.
If someone drains my accounts, I'm definitely screwed.
echo 1 | sudo tee /sys/devices/platform/thinkpad_acpi/leds/platform\:\:micmute/brightness
is enough to turn the LED on without muting the mic.You ring your bank and it's reversed almost instantly. Your photos on the internet you have no way of doing anything about them, they are there forever.
This never really registered to me, before a former colleague commented on the nonsense with people putting tape over their camera. If an attacker has access to your camera, or microphone, then they have access to pretty much very thing else. The difference in damage is negligible, it's already total for most.
If people are truly concerned about the camera in their laptop, then keep the computer in a dedicate room, shut it down when your done (or close the lid, if it's a laptop).
Sure it's kinda dumb that the LED is software controlled and that there's not a physical switch for turning off the microphone, but even having those things done correct doesn't negate the amount of damage someone could do with they have that kind of access to your devices.
A young Danish woman had nude photos leaked by an old boyfriend. She had her friend take better pictures and posted those herself so now no one can find the original photos. Not suggesting that as a solution, but I thought it was a pretty fun response.
This is obviously incorrect.
There is lots of software that can get access to your camera/microphone but not have access to anything else, like browser-based applications. And on Mac even locally installed applications are limited; getting access to user data directories requires a separate permission grant from webcam access.
You might also simply have nothing incriminating on your machine.
