It has been pointed out several times that this is a security feature, so Daniel is only doing this to protect his user base.

Imagine it the other way around: Someone would have gotten hold of your credentials and is now demanding that Daniel close the account and pay out the remaining BTC to a specific address. If Daniel would blindly trust the attacker, your coins would be gone in no time.

So yes, you should actually be grateful that Bustabit uses such measures.
