It's a good decision for Swiss maybe, but awful for people. In my country who took loans in swiss franc used to pay $400 monthly (installment was $400 per month), now it's
800$ per monthWTF!!!

Leaving your currency risk unhedged... That is crazy.
True but I bet lots of fx traders trading a few pips up and down were wiped out when they removed the peg. Its the sort of thing that would happen to me, sell the CHF just as they unpeg it!
