Using common sense here; technically, WG didn't rob anyone or cheat anyone out of anything. You purchased GOLD BUNDLE to buy something using in-game currency (what you bought). I don't think a "lawsuit" or whatever some have mentioned, is going anywhere, simply because, you got what YOU paid for. You PAID real $$$ for GOLD, which you then used as in-game currency to purchase a tank. Wargaming gave you your GOLD back (which you purchased with real money) and took the tank away and kept their promise that "Fearless won't be sold.". Doesn't seem like a problem to me, and I understand people are upset they don't get to keep their shiny IS-6 Fearless, but I don't think WG robbed you in any way, to be honest. Also, in the EULA (something you accepted when you made your account, meaning you said "Yeah, I'm down" It pretty much implies that WG can do anything they want, when they want and how they want.
Now, go and use that gold you have left on those sweet new Tier X Camos WG released or free xp up the line a little with the new French tanks! (No seriously, E5 camo and IS-7 camo are awesome!)
I feel bad for Sly having to deal with this mess, not even his fault.
