Isn't Facebook still doing this? You have to explicitly restrict FB access to your microphone or they will use convos to inform advertising ... or conspiracy theory?
I wonder how many people would remove FB if they knew this. I'm one of the people less bothered by internet advertising (I commented to this about 3 days ago re ad-blocking and cookies) and to me it seems amazing people accept this level of intrusion.
