I think they try to keep the value of this portfolio (as in the past) as low as possible .... Should it be, there will be problems with the investors! So much portfolio ".. behind the scene .." (are the words of the company !!) can not be simple disappearance. (Remember screenshots and many other facts)
It's a solution for which there is no problem. If it had value in the marketplace it would have been sold, or implemented, ages ago. AntFarm is doing it with their own technology, why would it be necessary to buy Clipstream to do the same thing?
