Is web 3 a misunderstanding word for some gambling crypto projects? I've come across few gambling / crypto projects that claimed to be a web 3.0 online casino and other but they still ask for KYC.

The definition of web 3.0 had everything to do with decentralization, block chain technology and token based economics as per what Wikipedia illustrated so why is identity/ verification integrated?

Is this just a misunderstanding of what web 3 actually is? Or it's a way to attract people/users to make them think that their platform is more advanced?.
