Of course it's the NDA's...they can't say anything, they are so bound up in them....I'm not sure why that is not a good enough reason for so many here. It's been like this for some time, likely all of the NR's provided to this point had all parties agreeing to the wording.
This is really simple to me....I'm not happy about the s/p either, but the reasons seem fairly clear.
The company can't say anything because they can't.
I know this would have little to do with the PO, and that part still is a mystery, other than to say the banksters are being brought to the trough.
