Well, BTC-e repaid 55-60% of funds immediately. More if you waited until WEX was launched. So clearly redress was possible, just not of the "legal proceedings" variety. The obvious move was to take that money and run, not keep all your money on the new exchange. But alas, crypto traders love to take unnecessary risks.
If Bitfinex or Tether had most of their fiat money seized, you think they would spin up a refund process like BTC-e did? I would expect much worse results through the court system, especially given the dodgy jurisdictions where they are organized.
Bitfinex could've chosen bankruptcy with their Bitgo hack. Instead they did a cludge to stay afloat. And they have had a large amount of fiat stolen from them by Crypto Capital. Again, they've limped on.
Both they and their users have Gox to look to to know what happens if they go down the fully legit route.
If there was some way of knowing the original BTC-e team was in place then at least you have some track record to reassure you. Clearly the original team wasn't in place by the end so it's full facelessness which isn't a good look.
If someone turns up today saying hello we're back how do you know if there's anything legit about them? They may control original addresses but private keys are easily stolen.
