You are meant to keep your hand in a fist, i doesn't have too be white knuckled clenched though until impact, Therefore you are both right and wrong :P

I think you are seeing very bad examples or gkr sparring/fight potential. Get yourself along to a tournament and watch the open division, or check out some youtube stuff maybe?
It can get quite impressive even for "non-contact"
