I know this because you can browse for something on Amazon on one machine, then find ads for that item on an entirely different machine - but one that's using the same WiFi.
Good luck buying a surprise present for a Significant Other. If you try, they'll see ads for it on Facebook.
This is all fairly straight forward however, what blows my mind is Facebook makes recommendations of friends that I've NEVER had any digital interaction with. For some reason it picked up the kid who stocks the craft beer at my local family run grocer. Literally only talked to the kid face-to-face. No phone number, no texting, no contact entry (not that I share those with Facebook anyways). That made the hair on the…
I had a similar situtation where Facebook recommended that I friend a coworker that sat next to me.

Based on the high intersection of two sets of SSIDs names visible from two devices at the same time, you can decide two people were in one room together. If this happens regularly, you can be quite confident people "know" each other in some way, which can unveil many surprising "friends" recommendations.

There is some process that is running a spatial join. You were both logged into facebook at the same time, and were in close proximity. I had a similar situtation where Facebook recommended that I friend a coworker that sat next to me.
I am working at FB but not in ads or related team. But I had talked to a person who is directly working on it. Amazon is different to other AD buyers. Amazon does not want FB to know what customers are doing on its own site, so there is no FB tracker on Amazon at all. However, Amazon can choose what ad to deliver to you on FB backed up by its own team.

Interestingly, this doesn't seem to work for me if I have uBlock Origin enabled. However, nothing is logged as blocked in uBO, so I can't tell what it's doing to break it.
Same with Privacy Badger. I think it's the "Prevent WebRTC from leaking local IP address" option in the General Settings, except that mine is unset, yet they say the "Default options" protect me so I'm not sure if it's partially set by default anyway.
