Seriously? The one person who seeks licensed legal advice and follows that advice, at his own expense, is getting pounced on?
Picture yourself in his position, for just a minute. You make an appointment with a corporate attorney. You walk into his office and have to explain bitcoin, then explain bitcoin mining operations, then explain offshore securities exchanges denominated in bitcoin, then explain this exchange's controller going rogue and shutting down operations without providing information identifying just who holds shares in your corporation.
Now, picture the number of times this guy asks you,"What the fuck were you thinking?" during this conversation.
The attorney is going to try to correlate this to something he understands and can defend. He obviously wants to establish identification of partners in the corporation, or at the very least, counter parties in the various contracts.
I understand the unwillingness to reveal your identity to some random Internet dude, even if he has been paying you for months. However, this legal approach is laying the groundwork for a sustainable operation. The alternative is calling a halt to the entire thing.
He could be a total bastard and open a temporary exchange for people who are willing to disclose ownership and use that for the cost basis for buyback. Undoubtedly, he or another party could suppress prices for the period necessary to buy shares back for satoshis on the coin.
Cut him some slack and think for a minute.
Probably a good time to remember just how large an operation "Gigamining" is. It's not some guy in his mom's basement looking for weed money, and with the legal ambiguity surrounding what he does - if he isn't paying legal fees now to move Gigamining away from the darkness in legally gray territory, he'll likely pay much, much more later, even if he were to win future cases. Unfortunately, the cost of "going legal" is also pushed onto unit-holders, who didn't sign up for this, and are rightfully pissed. It's a shitty situation. -But, the alternative could be Giga's facilities and house being raided with all electronics confiscated, resulting in a near-worthless operation.
Think of it this way -- Giga's name and locations are (roughly, at least) known. The SEC has been prosecuting and investigating people who've issued some form of security for BTC. Giga's under much more legal scrutiny now than earlier this year, and now the legal shield of GLBSE (which was responsible for complying with many regulations, previously) is no longer in existence - so now all that legal risk's on Gigamining/VPS, which previously operated in a legal minefield even ignoring the legal risks Nefario or another exchange would take on. It's very possible, and probably likely, that Gigamining would be worthless within a year given the operation is high-value and no longer afforded the legal protections of an exchange taking most of the regulatory risk (Giga effectively has to issue some new security or figure out some other way to pay back unit-holders - and he's surely being watched by regulatory agents).
