Worth linking to these 2 posts on my blog. 2.5 years ago, the thing is, Facebook has been evil for years. I stopped using the service 5 years ago but had removed a ton of my data from the site long before that. The political data was used by the Obama campaign in 2012. None of this is new. Better late than never on mainstream people catching on but it’s a little late to finally be concerned about what Facebook and its partners know about you.
