The cases were handled exactly the way the procedural rules require, and it's exactly the way corporations avoid lawsuits every day. A plaintiff has to state enough factual assertions in their complaint to satisfy every element of the cause of action they are asserting. Fraud, specifically, has an even higher threshold for what must be stated in a complaint in order to avoid immediate dismissal. If a plaintiff doesn't meet this basic threshold in the complaint, judges are supposed to throw out the lawsuits so judicial resources are not wasted and defendants are not subjected to the harassment of frivolous lawsuits. You seem to be criticizing judges for doing exactly what the procedural rules require them to do. However, if you are unhappy cases were dismissed so quickly, you only have the plaintiffs' attorneys or the plaintiffs themselves to blame.
