I deleted my account back when I first realized that Facebook had the ethical standards of the Gambino family, maybe ten years or so ago, and I wasn't on it for very long in the first place. If you do decide to bail on them (and good for you if you do!), bear in mind that you'll likely find it trickier than I did; some people didn't bother responding to the emails I sent, and I've since lost contact with them, and things have only gotten worse since then. You'll find a surprising amount of content gated off behind Facebook's walls- for example, I had a devil of a time in the election last month because several candidates only kept a Facebook page. If I ignore them, am I being practical, or just spiteful?
The are alternatives out there, but while you may persuade a handful of people to set up new accounts, they're not likely to stick to them. Facebook, like EA, has its potential customers divided into two groups: for the first group, it doesn't matter what the company does, they'll stick with it. For the second group, it doesn't matter what the company does, they've already left. (Truth be told, I don't even know what they've done this time; I'm guessing it's yet another massive privacy violation.) My point is, you're not likely to see a massive exodus. Should you leave? Yes, absolutely; even if this particular case isn't especially heinous, sending the message that you have standards is a good thing to do, but you're likely to become a bit more isolated than you already are.
