Facebook is sorry....it was caught
Facebook, Google, Twitter, you name it. They all track for financial gain and easily take advantage of 2018 mindsets to do it.
There is no privacy any more. People freely give away their own information for a moment in the spotlight and/or personal pleasure and, as these incidents prove, they'll freely give away their best friends' privacy for a moment in the spotlight and/or their own personal pleasure.
Facebook is claiming to be sorry, but it is only sorry for two things. First, that republicans were able to take advantage of the same type data they had previously freely given democrats and second, that they were caught doing one while not stopping the other.
