It's perfectly possibly they'll increase privacy, in the sense that instead of blasting updates to everyone you send them to specific people, with an autodelete. This doesn't interfere with tracking. Most people, when they think about privacy, think about the disclosure of specific posts to unintended audiences. They often don't think about the tracking beacons silently categorizing everything. So in short, it's perfectly possible to have "privacy friendly" Facebook - if your definition of privacy doesn't extend to being free from ad trackers.
