All these companies know they're a target for accountability now, and even many people inside of them acknowledge a need for reform and possibly restitution. Your comment seems focused on the practical matters of these lawsuits (many of which probably are frivolous or will otherwise be lost), but what really matters are the unsettled societal costs that transcend them.
You may feel that accountability is being "misplaced", but it's much bigger than ambulance chasers and grandstanders. People are genuinely concerned about real problems and are hungry for some kind of action on them.
