For me it’s the paranoia surrounding webcams. People outright refuse to own one and I understand, until they go on and on about how they’re being spied. Here’s the secret - unplug the damn thing when you think you won’t use it or haven’t used it in a while.
They, whoever it is, can’t really spy on you on something that’s already off and unplugged!
It’s a bit late to worry about internal mics when everyone has their phone on them at all times.
You can take care of privacy on your personal hardware, but with work issued devices, you can’t.
The need for a solution regarding one angle of a problem does not invalidate the value for a solution regarding another.
