why do you need a license to use something that is posted and publically accessible? A license makes sense for a copyrighted work that you are copying, but for a web service it's less clear.
If I had a physical analog of facebook (a bunch of photos, a travel journal, and a list of my friends) and left it on a table, then do you need a license to pick it up and review it? No. So why do you need one if I do the same thing as a web site?
