This is an absurd urban myth, and it's embarrassing to see such nonsense on this website.
"The Leading Automated Content Recognition Solution"
"Content ID Software & Information Services for Networks, Cloud Platforms, Devices & Apps"
"Make your smart device, application, or platform content aware in the presence of media streams or ambient audio."
Ambient audio. In other words, they turn your phone into a listening device then analyze what it hears for commercial purposes, albeit supposedly only for picking up the sound of copyrighted material.
But even if was, then your logic would be absurd. You would be saying that every urban myth is true because a single example was true. That is nonsensical.
And no, I wasn't implying anything - I'd like some arguments regarding your point. And saying 'thats nonsense', 'you're wrong' does not make any of your points valid.
It's not up to me to disprove such an absurd extreme claim, it's up to the OP to prove it.
That's how the world works, or else everyone would spend their entire lives having to disprove the claims of cranks and conspiracy theorists.
You haven't answered any of my questions so there's that.
Things like Amazon Echo exist and are used for all sorts of purposes, including making purchases and being available for law enforcement.
Gmail is an advertising company who actively listens in on the conversations you have on on their services (i.e. gmail) and uses it to display ads.
Facebook is an advertising company and data mines the hell out of all the data about you they can get their hands on to be able to sell targeted ads.
The specific use-case of "listening to you talk with your mouth, analyzing it and then showing you ads based on it" might not be explicitly be mentioned in the Facebook TOS, but it's the very natural extension of their business model keeping in pace with technology.
So far the evidence has been "I talked about x and a few days later I saw an advert for x".
It's absurd cringy nonsense.
