Why I’m Leaving Facebook

It’s not strictly true, I will have a facebook ID again in the coming months, but it will be an output only ID. By that I mean it will be an ID that I can post things to, but little more than that.

As I said in my “evil empire” post, I’ve become more and more concerned about not just what data they collect, but what you can learn from it. They sell our data, and it’s pretty easy to drill down on the data and learn all sorts of things, even though the data is supposed to be anonymous.

The problem with this is not just what facebook can tell, it’s that to a degree it is a very biased view of who we are. For the longest time, the standing joke was:

if it’s not on facebook, it didn’t happen

But you know that’s not true. When was the last time you posted about your intimate desires, or genuine mistakes, or arguments you had with important people in your life, or private details of your dealings with banks, managers and so on. These all go to make up who you are, what makes you tick.

What facebook has is a simple snapshot, someone who is vastly different online than offline. Yeah, facebook knows I’m liberal, likely not religious, I read the Guardian and the New York Times and probably trust them for news as I spend more time reading articles. Facebook knows I have a generally negative view of the new President and it thinks it know what products and brands I “like“. The data says my “psychological gender” is more male than feminine, but not by much; I’m pretty laid back but do get emotional.

Our data is sold in bulk, using specialised tools, you can target data geographically, based on numerous categories. It is supposed to be anonymised when sold, but it’s relatively simple to identify. This week in Ireland the American Civil Liberties Union [ACLU] was trying to defend our privacy rights, when facebook moves our data between Europe and the USA. Europe has much stronger data protection rights. Facebook of course argued against that.

If you are not convinced, watch this video from the creators of Data Selfie, a chrome extension, see how what you do [on facebook], leaves a data trail to the person you are [on facebook].

The lack of control over our data is seriously concerning. Even though I’ve already deleted the primary facebook app from my phone, as well as Messenger. You can’t even see the data, I fear that facebook has data I can’t control, can’t delete, and somewhere in a facebook data center, I have a twin, someone I don’t know.
