Because it is the hottest topic to talk although I believe those who likes to judge like that are not even gambler . If they are real gambler no matter in fiat or crypto, they should have noticed that KYC is not something "taboo" these days because most casino has the right to request their players to complete KYC based on their official terms and conditions. I think they are just too worried about it but they do not know the fact because they never tried.
