After significant protest, Facebook is now allowing users to opt out of Beacon, the advertising system that links purchases from some vendors to facebook newsfeeds. This doesn’t address my main concern, however, since this just means that the data won’t be published on the newsfeed; Facebook still stores the data, a creepy Google-esque violation of privacy. My understanding of the process is that affiliated vendors ask for an email during a purchase (almost all online transactions ask for an email address), then send this email to Facebook, asking if that email is a user. If so, then the vendor send the purchase info to Facebook, which would then post the details to their newsfeed. So, I’ve been making sure to make purchases with email addresses unknown to Facebook.
Zuckerberg has updated his blog apology, now with a paragraph at the bottom indicating that Facebook is addressing this main concern:
Last week we changed Beacon to be an opt-in system, and today we’re releasing a privacy control to turn off Beacon completely. You can find it here. If you select that you don’t want to share some Beacon actions or if you turn off Beacon, then Facebook won’t store those actions even when partners send them to Facebook.
I admit I’m skeptical, but it’s a start?
