To spend money on re-activating the stock would require money and employees. There is no one really working for the company and from what I can tell there isn't any money. Why would anyone even spend a dime reactivating an incorporation if they aren't going to do anything with it.
Many of us thought the stock might be used as a shelf stock for SkyNet to do a reverse merger. But, you would generally leave the incorporation active and keep filing with the SEC so you would have a cleaner road for the reverse merge, so that has come to past.
But, then again, I think SkyNet isn't worth anything, so I wouldn't want merge into that anyways.
