If this is all about fair and why we do care about gambling? I think for others they always care if the site is provably fair or not because they are just wasting their time while they are playing for nothing.. but for others they are just gamble for fun not making any profit they are ok if they are lose a lot even the site is not provably fair but for me we need always to check if its if provably fair or not that is why we are care about fair.
completely agree with you actually I have the same way of seeing this
Those who are just doing gambling just for fun doesn't care about if it is fair or not, what important to them is they are enjoying what they are doing, and for those who are doing gambling to earn money? of course thy do care about their winnings and mostly about their loses. Gambling do have only two types of people, those who are lucky, and those who are not, I guess it is pretty similar to those who care and don't care about the profits they are making in gambling.
Gambling is a very risky thing to do in the first place, so it would be better if you are going to give a damn care about it to avoid losing most of the time, because gambling is no joke.
