Optimism ends when the game is over. You can be optimistic that your team can win, but when the buzzer sounds and the game is lost, it is no longer optimism, it is foolish denial.
The boxscore is posted in the court records, and they very clearly document the liquidation and shutdown of this company. Everything was sold, including the plant and its patents, to LCYB. BioAmber has no assets, no employees, no business operations, no corporate charter, nothing, but you have to be willing to read the boxscore.
Nobody likes losing money, nor do they like acknowledging they were taken in by a bunch of con artists who made up a lie about a liquidated company being bought out. But that's what happened, it was a lie used to flip the stock for profit, something that is very common on the OTC, happens all the time. The con artists have everyone's money now.
Most of the "debate" is folks pretending to believe when they don't, just some sort of weird sport where spouting BS and getting a response is some sort of "win," kinda pathetic, really.
