I appreciate that idea, however, I've been testing my own 'friend suggestions' and keep a strong track of my antics... also, it's become a hobby of mine to debunk each time someone says 'they're listening to my microphone!!!' Most of the time the 'listening to me' conversations are based on origin IP to insta/fb/whatsapp servers. One person talks about idea X, another person looks it up (either in the room or later at home by themselves), and now everyone who was at that IP together will get ads for X. What's more, Google maps uses Wifi SSIDs to get better location data when GPS gets a bit spotty... so, I'd venture to say it's a small step to associate accounts and make friends.
