Unless you work at FB and can prove anything, with all due respect, it doesn’t matter.
Way too many people, myself included - multiple times - have experienced this. I’d hope someone who has not experienced it and does not work at the companies related to it would not be so vocal against it.
Fair enough, but my point is you just can’t prove either way and only add noise to the conversation. I’d like to hear from someone at say, apple or google, if the mics could be used or have been used before there were led indicators, for instance. But I guess that’s not going to happen.
