/metadata/link -> api v2 now forces user authentication?

That's a real bummer. I assume this is intentional (no way this would be accidental as it is quite a big change). There are only 2 reasons I can surmise -- 1) to drive sign-ups, and 2) further fraud/spam/leech protection. Neither seem reasonable to me, because the ability to quickly access a shared link's contents WITHOUT having a dropbox account has always been a major reason why I liked dropbox. The fragmentation of our digital identities is to the point now where forcing someone to create yet another account for something is foolish, even if you've been around for many years like Dropbox.
