Does anyone have a link that doesn't require me to login to see this?

This is a google groups quirk.

If you are logged into a google account it will prompt you. If you sign out of your google accounts then you can read it without being logged in.

That happens when google groups detects a cookie indicating someone logged in to google at some point in the past.
