This is not what certification of a class action lawsuit means. It's procedural, not substantive and doesn't weigh in on the merits of the lawsuit. It's about the mechanics of bringing about action representing a potentially huge group of class representatives. The article then goes on to speculate about how Anthropic will post bond for the billions that have been awarded while trying to fundraise, so the clickbait title is backed up with "what if" fan fiction and there's nothing substantive here.
