You make some good points, i think we are all hoping that they will return in some form as i do not think their intention is to run away.
Of course US has made problems for them, mostly seems because US wants to target anything with Russia as they are paranoid.
It would also be good to get some message if its possible from BTCe guys even if its a "Hello World" but also understand that maybe Twitter account is comprimised that they cant say anything right now.
In any case lots of legit users still holding some hope of a return soon.
