Oddly enough, if you are not logged into Google at all, you can view Google Groups public content without hitting a login prompt. But if you are logged in to Google in another way -- perhaps in a stale way -- attempting to view public Groups content often triggers a login page, and there's no option to skip it. (Only by completely logging out elsewhere is the path cleared for non-logged-in access.)
A lesson that even at Google, single-sign-on is wonky.
Sort of.
