To the extent that headlines matter, I'd way rather that people worry about the privacy risks of de-anonymizing technology long before it's at the point where it's a practical issue. If we only worry about it when it becomes an actual issue already being, or about to be, applied to unambiguously privacy-invading matters, then, well, that's the way we've already done it and it's too late now—why didn't you bring it up earlier? I'd also prefer to avoid the "what do you have to hide?" issue. Maybe someone, for whatever reason, does have something to hide; if they intentionally play chess anonymously, presumably they intend to do so. It shouldn't be up to me to decide whether or not their need, or even just desire, for privacy is legitimate. (Of course, it's already too late—and has been since, at the very latest, the AOL incident—to worry about the onset of such de-anonymization, but it's always (or only almost always?) better to face inevitable future problems now, rather than waiting for that future.)
