If the Biden Admin "said" something, the stock price would go up. That would be contrary to the government's interests. Because in an SPS-to-common-conversion, the lower the commons' price at the time of the swap, the larger the government's share of the pie.
So the more secretive Biden operates, the greater the dilution - and thus the greater the gain from the cramdown.
Biden's "silence" could therefore be interpreted as greed.
I probably don't need to emphasize that the government and the shareholders have opposing interests.
