1) Saying something like that could adversely affect share price
2) I could be wrong, but I think winding this down would pretty much guarantee losses for most investors. This could be blamed in part on the 3 BTC floor that was imposed, but even without that, I don't think the operation has been running long enough to earn enough for any investor from prior to that floor to break even, and anyone who got in lower got in late enough that they still probably haven't broken even unless they sold for a gain.
And a positive one:
I suppose winding down would mean selling the equipment and distributing those earnings as well as saved funds, so maybe that wolud negate my concerns from (2) [and I suppose (1) would become irrelevant for anyone that could hold while waiting for that to finalize].
