No, I mean for new users they are doing away with the public folders. You can now get a public link to any folder in your dropbox, it's just it goes to a splash page where they let you view the pic, or download the html. Basically new users won't be able to use their dropbox public folder as a webserver because of that anymore, no hotlinking images with dropbox links.
I know. My point was that this isn't a good justification to remove the public folder, as people could always put HTML files there and it was safe to do so.
