This seems pretty useless. The only scenario where it gives FB more information is where person A takes a picture, gives it to person B through some route other than FB and then person B posts it on FB. Any other scenario and FB does not need to compare dust specks.

I don't want privacy controls, I want complete control. I'm stoked about the Librem 5 project, and I hope it succeeds enough to not disappear in a couple years. I just bought a phone, but I'll likely buy the next rev if the first one works out. I don't need much from my phone, and as long as I can make/receive calls/texts, browse the web, and can get consistent security patches from the community (e.g. some Linux dis…
Complete control is easy. End to end encryption. Don’t let them see what you’re doing. MAIDSAFE network!

I've always been floored that people leave their location services turned on by default. I have mine on for no more than a few minutes a month. I only turn it on when I'm in an unfamiliar location, don't have my bearings, and looking at the map alone isn't enough to help without GPS.
Fun fact: my Android phone battery was being sucked at a fast pace last month. I don't remember exactly how it presented itself in the UI, but I ended up figuring out that the Google app was the culprit, because it was using the GPS... which I had explicitly disabled. An internet search showed I was not alone with such problems, and that the solution was to manually revoke some permissions for the app (thankfully it…
For location also Wi-Fi is used. So GPS can be turned off but they can track your location by looking at the available Wi-Fi spots around you.

I feel there is no reason to expect Facebook would be content with data hosted on just their platform. With camera fingerprinting, they could be relatively sure who you are on other platforms like Twitter, VK, Youtube etc in cases where the user doesn't use the same email/name.

Cellular carriers sell your real-time GPS location even if you turn off your phone (GPS chips operate outside the network) Proof: https://www.zdnet.com/article/us-cell-carriers-selling-acces...
The article literally says "cell phone location data from nearby cell towers. It's less accurate than using GPS".
by comparing the accelerometer and gyroscope readings of each phone, the data could identify when people were facing each other or walking together. More evidence we need far more privacy controls in mobile operating systems.

> Though very uncanny, this is rather easy to extrapolate even using the basic facets FB has available. But the most overlooked is photos. They are offline beacons and are to offline tracking what websites are to online tracking. For example you and a group of 10 other people took photos at the same location which FB sees as a small gathering of intimate friends. It will need to qualify the location is not a public restaurant to be sure its an intimate gathering. The chances of you connecting with that person are then really high. And if you are and the other person are in each others photos, then it's almost a certainty you will end up connecting on FB should FB recommend the connection. The more connected FB's network is, the more it can extrapolate based on commonalities from the first degree graph of your network. It's also the reason why Google is betting so heavy on photos and offering free unlimited storage -- remember, there's no such thing as a free lunch. Google wants to build a social network graph based on location and facial recognition to draw on proximity. With AI this will get even more uncanny. For example a wedding will have a certain photography profile (number of pics taken, the time of day, the location and venue based on Google Maps or past photographing histroy, the lighting in the photos, etc). Once you throw AI into the mix you realize Google doesn't need to draw out any conclusions. It can throw all these parameters into the AI engine and draw up proximity. In this case, Google or FB will not be able to tell you how they drew the connection, because even they won't know. All you can assume is the AI engine will take dozens of parameters today and hundreds tomorrow. Google's deep investment in AI infrastructure is a bigger testament to this.

But this happens quite often, like every time people get together.
I think people who use FB generally share photos with their friends who are also on FB, through FB.
