Yeah, I haven't actually used facebook for anything in years, so now I'm deleting my account and I will use a temporary phone for any future situation where I need it.
I will also be going out of my way to spread as much FUD among my less tech savvy friends as I possibly can.
Why don't you just delete the Facebook app from your smartphone? That way, Facebook won't have access to your contact list. Therefore, this should not happen.
I'm a casual Facebook user since like 2008, but I never even considered installing any of the Facebook apps on my phone.
You will still be tied to a unique identifier and tracked all over the web because your browser fingerprint (yes, it's probably unique: test here https://panopticlick.eff.org/) will be reported back for every site affiliated with an advertising network affiliated with Facebook.
I just tried it out. The site acknowledges it tested out ~6M devices so far. It's not that big of a number actually. My browser turned out to be unique even though I'm using a pretty common method (basically just run Chrome on an Android).
I've sent the version of Android (which was falsely detected because I upgraded to a newer version, but I'm still sending the info about the older version, so I'm assuming this is a bug), my Android model (and build) and my timezone. Anyone who bought the same model from my country (and possibly even the surrounding countries) would probably get the same fingerprint (unless he's using a different browser).
I will also be going out of my way to spread as much FUD among my less tech savvy friends as I possibly can.
Go Zuck yourself, Mark.
