TechCrunch interprets this language as a sign that Facebook could let outside sites take it upon themselves to sign users into Facebook Connect.
The ACLU of Northern California has already flagged this proposed change in policy as a potential privacy threat.
While Facebook says that users will be able to prevent sharing information with third-party sites, it looks like they would have to opt out to do so. Obviously there's nothing inherently wrong with enabling people to share their names or photos with other sites. But it's hugely problematic for Facebook (or any other service) to enable those outside sites to grab that data on their own.
