It's a bit of a double-edged sword to claim that since Dow Jones and Reuters had to issue corrections in their articles, it means Wave is not at all culpable in the eyes of the SEC or in the class-action lawsuits.
A counter-argument can be made that if both of those respected, objective news organizations were fooled by the press releases, then yes, indeed, there may have been a problem with the content of the original press releases as issued by Wave.
