Yahoo! Inc. (NYSE: YHOO) was sued in federal court in San Jose, California, this week. They are being sued over claims that they are invading users privacy by scanning their e-mails to better target the ads the user sees. Google and Linkenin have all recently been in court over similar claims. I for one am extremely happy to hear this because no one likes companies to scan important and private material in their emails so ad agencies and fortune 500 companies and find us and bombard us with more ads.
