Earlier quoted context omitted.
Not sure what the problem is. I have complete control over the privacy settings of all my accounts. After reading the post, I think the problem is the poster made a choice before this not to use the privacy features.
When you have HN readers complaining about this issue, then we can be fairly certain that the average user of Google's products will have a very difficult time finding their way to the "privacy features" controls, and in effect Google has already made these privacy decisions for them.
So, I go back to what I was saying: did anyone using the privacy settings available have their privacy setting explicitly overridden, or was is just people not using the privacy settings available, and then getting run over when they realized what they had allowed opened?
Edit: I get downvoted for asking questions. Apparently, not following the torch-bearers blindly is frowned on.
