Shortly after 23andMe confirmed that hackers stole ancestry data of 6.9 million users, 23andMe has updated its terms of service, seemingly cutting off a path previously granted to users seeking public accountability when resolving disputes.

According to a post on Hacker News, the "23andMe Team" notified users in an email that "important updates were made to the Dispute Resolution and Arbitration section" of 23andMe's terms of service on November 30. This was done, 23andMe told users, "to include procedures that will encourage a prompt resolution of any disputes and to streamline arbitration proceedings where multiple similar claims are filed."
