I dont see how Bitfinex would have lost anything. Traders are the one's who lose out because someone was able to basically rig the trading. But as a platform, Bitfinex engine was simply matching trades meaning traders positions were being closed and trades were being made "as normal". Bitfinex would me making %fees from all that. Need to be clear here, their platform was exploited, but Bitfinex did not suffer losses that I can see, only traders. I feel sorry for anyone who was bankrupted by this... so rolling back those trades was the right thing to do for sure. But I think you should probably talk with Bitfinex in private, if you dont get resolution then maybe you can be more vocal, but until then, it would be better not to create noise here.
