It's easy for the media to stimulate the minds of the people and letting them believe that they already have found the solution in stopping bitcoin's long-reigning volatility in its markets, by publishing a single report without any substantial evidence that market manipulation is indeed that cause of all the market's volatility. I think that manipulation plays a part in volatility but it's not the only cause of it: there are other more plausible reasons that dictate volatility, and one simple fact is that bitcoin is a globally-open market without any restrictions as long as you comply with the prerequisites on an exchange, and then you can start trading freely.
