That's been happening for well over a decade now, and while "respectable security researchers" call it bullshit... there's simply too much anecdotal evidence for it to happen organically.
The reality is they don't need to listen.
They have so much data on users.
It just goes on and on and on.
People think they are unique but they are not as unique as they think.
NONE of that data can predict a random occurrence discussion that goes in a specific direction.
A great example is something that happened to me in 2015. One night I was out with friends, and one of them had a really bad panic attack. The next day I was discussing it with a colleague during a smoke break, who recommended he gets a clip-on pulse oximeter. No searches, nothing, literally just a half minute detour in our chat. I repeat, nothing was typed in or looked up or in any way entered into any computer intentionally.
Five minutes later we're sitting in front of our respective computers and I start getting ads for the very thing. Mind you, we're still at a point where nothing noted during this discussion was entered into any computer. Explain this.
Friend, or friends discussed said panic attack on big tech social in DMs or something. Obviously, you follow your friends, you are likely to go out on Saturdays with them, maybe even your first name was mentioned in their messages, you are now tied to an advertising angle for 'Panick Attacks'. Data brokers buy this information, serve ads. This is just ONE way the data may have been inferred. This doesn't include contact scanning, location services and so on.
No such discussion happened. As per above, that group of people were super toxic and couldn't care less about this specific person...
At most the remaining people would've mentioned how his panic attack inconvenienced their night out.
