Hours later, Facebook responded back, via a comment left on tech blog TechCrunch by Facebook engineer Mike Vernal. He said that Google had been inconsistent on the issue of whether exporting information about a user’s friends from a social networking site was a standard — or good — practice. Wrote Vernal: “Our policy has been consistent. The most important principle for Facebook is that every person owns and controls her information. Each person owns her friends list, but not her friends’ information. A person has no more right to mass export all of her friends’ private email addresses than she does to mass export all of her friends’ private photo albums.”
He contiuned [sic]: “We strongly hope that Google turns back on their API and doesn’t come up with yet another excuse to prevent their users from leaving Google products to use ones they like better instead.” You can read the whole comment (plus reaction) here.
