Not sure why you're displeased about it? It's a coin totally separate from wbb and if anything will help wbb exposure in the long run, especially since wbb will be a 'main' focus coin on 1ex in the ecosystem of things.
I'm sure there are people that hold wbb that didn't want to buy 1ex shares so the coin is of no care/worry to them since they didn't buy shares. Meanwhile other people that hold wbb and know how good the dev is also bought some shares and will enjoy 1ex free coins to hold. I know I bought just a bit of shares to get some % return from the exchange volumes...but now with 1ex coins essentially it's 4% staking profits from this coin, which I see the dev is rewarding shareholders with - pretty cool. If you took the risk to buy shares and believe in 1ex then it's a nice bonus. If not, no biggie and keep holding wbb as it's going to rise regardless.
It's closed source and can only be held and traded on the 1EX exchange with LOCKED pegged $100 USD value...so you can't exactly dump it or trade it anywhere else lol. If anything it's more as a placeholder for those invested into 1EX to push them to hold because they'll just be making nice interest over time, that's what the main goal is I think (sure people will sell within 1ex i guess). I'm sure you'll be able to somehow "trade" the coin on 1ex itself, I assume with those that want to buy some and make interest as well.
Anyway if you understand the grandscheme of things I don't think you need to worry about wbb in anyway. 1ex coin is 'its own entity' so to speak.
