As of about an hour or so ago, it still wasn't fixed. Clicking "No, thanks" on the first Buzz popup screen means nothing - Buzz still gets enabled, still auto-populates a big list of followers and followees, and still makes that list public.
I had the same thing happen not 10 minutes ago. I logged into a rarely used gmail account, got the Buzz landing page, clicked "no thanks" and then was redirected to my inbox. Buzz was there and active and had added followers automatically.
