this happened with a few co-workers. They got ads about things we spoke about at work and shared it with the group on slack. After nagging them about uninstalling FB for a while, the targeted ads scared some of them to finally uninstall the always listening FB spyware from their phone(s)
I once dropped my work laptop and snapped the plastic housing on the charger plug. I only discussed it verbally with my manager and said that I, as a consultant, would replace it at my own expense. Before I'd had chance to search for and price one up adverts for laptop chargers started following me around the web.
It could have been that she then searched for a charger and being a small company we all shared an external IP address, that we also shared the ads... or it could have been that spy software on my phone had sold our conversation to advertisers. Either way, mic privileges were locked down and ad and tracker blocking efforts doubled after that.
