Speaking only for myself, and not in any way, shape or form as an EO Mod, Facebook is evil. When Facebook first went public I took a look at it, created an account, and immediately knew it was bad news. Already knowing how it was used in academia, it was clear to me what would happen with it going public, that the whole point was to suck people in, obtain personal information from people for free, and then sell it to advertisers.
Not too long after my first look at Facebook Mark Zuckerberg stated that there is no expectation of privacy on the Internet, nor should there be. That told me that, as with most things, if it can be abused it will be, and Zuckerberg absolutely would abuse things. And he has.
And it's only become worse with his policy of political activism, including blatant censorship of political views he disagrees with. Social media has become the public square of our time, and it should be treated as such.
I won't do Facebook, and it's not because of the aggravation or the drama, as you will find that everywhere, including here, and even in personal email.
I won't engage with Facebook because they claim to "connect people" while being oblivious to real human beings.
Facebook's imperative to “connect people” lacks the one ingredient essential for being a good citizen: Treating individual human beings as sacrosanct. Something that is sacrosanct is something too important or too valuable to be interfered with or dismissed. To Facebook, the world is not made up of sacrosanct individuals, but of connections between them. The billions of Facebook accounts belong not to “people” but to nondescript “users,” collections of data points connected to other collections of data points on a vast Social Network, to be targeted and monetized by computer programs.
There are certain things you do not in good conscience do to humans. To data, on the other hand, you can do whatever you like. And Facebook does whatever it likes.
