Some privacy experts said that Google had made matters worse by making it difficult for people to hide their lists of Buzz contacts after they realized that those lists had been made public. Some users assumed that they could simply turn off the Buzz service, but that proved inadequate.
“You want to have a simple rollback mechanism, so once things are not what you expected them to be, you can get out quickly and not have to play a game of Whack-a-Mole,” said Deirdre Mulligan, a privacy expert and assistant professor at the School of Information at the University of California, Berkeley.
Google said it was planning to address that issue soon.
