Facebook attack on google unveils its own privacy flaw
Facebook was griping that Google is getting information about its users without permission. But some information that users share with Facebook is available publicly, even to people who aren’t their friends in in their social networks – or even are members of Facebook. It’s not because outsiders raided the service and exposed that information. It’s because Facebook chose to expose it.
Facebook used to have an implicit promise with its users. Basically the deal was what goes on Facebook stays on Facebook. But over the past couple of years Facebook has chosen to alter the deal. Certain profile information became available outside of Facebook, easily searchable via Google and other means. (Users can opt out of showing this but relatively few do.) Some of that profile information includes a few of the people on the user’s friend list. By repeatedly pinging public profiles, it’s possible for Google or anyone else to figure out pretty much all your friends.
This information is a lot easier to unearth from inside Facebook, but actually logging into Facebook to purloin information would indeed be troublesome. For one thing, it would violate the terms of service agreement. Is Google doing this? One of the Burson operatives implied that it is. But Google says the company does not go inside Facebook to scrape information, and I find this credible. (If Facebook has logs to prove this serious charge, let’s see them.)
When Google launched Social Search, it also said specifically that it was not going to learn about Facebook connections by mining the Web as described above. Just how Google does get Facebook information is complicated, much of it seems to be by permission.
But even if Google did scrape information from the public web, would that be so bad? You can argue whether or not Google would be crossing a privacy line by doing this. (And, remember, Google says it is not mining that public information.) But it’s an argument with a pro and con. What you cannot argue is that is not Google but Facebook that puts some Facebook information into the open Web.
That is why Facebook’s campaign is so weird. If outsiders are going to examine how third-party companies get information about Facebook’s users, you can’t help but question why some Facebook information, by default, shows up on the open web.
