Are you against crypto gambling or against KYC? There are platforms where you may gamble without KYC, there is always a choice. At the end it is just a currency and a service, if someone thinks it is worth it, why not to do it?
I am not the op but my opinion is we should hate KYC as a bitcoin/crypto lover as the purpose of using bitcoin/crypto is to use it anonymously. But if we use to know your customer then there is no way to use the crypto/bitcoin anonymously. So, I personally dislike it. But you are right we have options too. It is something you do, or you have to do. I mean the maximum site will ask very KYC at any time. Only a few sites may not require to fill out KYC.
