Yunbi voting against the workers could be looked at as them protecting their customers. By voting against the workers, they are preventing the dilution of their customers bts. Dilution has direct negative price pressure and adds an additional variable to trading. Workers and development doesn't necessarily mean higher price.
Also there is no "social contact" that the exchanges need to follow, and constant vilifying of exchanges is going to hurt the bts price much more than an exchange actually using the system the way it was designed.
Yes.. there is.. BTS is a unique token beyond others that are on central exchanges. It comes with voting power to influence what happens in Bitshares. If someone is to be able to use an exchange, they are using it to exchange, not to have the voting power absconded by that exchange. This is along the same lines as the exchange taking any snapshots of sharedrops for themselves.
We have a mechanism for proxy voting... and if Yunbi can show that all their depositors accounts are in fact proxying to them because they want Yunbi voting for them, then there is nothing to argue here. This is being done with consent... even if it was a majority percentage and not everyone then I would accept that.. If not though, then this is being done without consent. Lets take a look:

Exchanges shouldn't be vilified.. I think they are a very important part to the virtual currency world.
Yunbi has far more understanding and familiarity with Bitshares compared to other exchanges, and they understand better than others the trust being placed with BTS holders in centralized exchanges in regards to voting power. They have somehow arrived at some twisted conclusion that now it is OK for them to vote with their stake.
A year ago when they were delegates taking money from Bitshares for their exchange they understood very well that using their balance to vote would not be well received. Why suddenly they think its ok when in the past it never was? What changed?
The only change now is that the voting power placed with Bitshares holders is far greater. So the message seems from Yunbi is, if you allow someone to have to much power available to them, they will take it without consent for their own purposes.
Again.. there are no arguments against this action if the individual account holders proxy their vote to yunbi in show of support. That would indicate a social consensus in support of them voting.
