> Facebook works directly with six data brokers, all of which allow you to opt out from their sharing of your personal data, everything from your email to your purchase history.

And that sort of explains everything.

I kept wondering how the info that keep to the Google-verse (search, Gmail) makes it to Facebook. Now I know.

Does it mean that Google collaborates with these data brokers? While it doesn't harm them directly, it seems like a myopic thing to do, arming a company that may undercut your sole major source of income. Yes, I imagine they take it directly from the device, but doesn't Google have control over the Android internals?

Also, I am in somewhat unique position. Being a Microsoft zealot, I still carry a Windows phone (v8.1) with slowly dying services. I almost don't use Facebook yet I still get these too relevant ads, mostly according to what I google on my desktop.



How much use do you make of Bing, if you don't mind me asking? Is it a case of mainly using it (as you are a Microsoft fan) but occasionally needing to refer to a Google search?


I am more used to Google which I use on the desktop, but when on the phone, I use both interchangeably.

When it comes to the US and global content, there is virtually no difference in the results. Google is much better in the local content and the knowledge graph results though, as well as the maps. Video search is better in Bing.
