If an ISP chooses to deploy a technology in a bad way, that is not the technology's fault. Even if most ISPs were just giving users a /128 address (which to be clear, is very much not the case), that would not be some kind of failure of IPv6.
The fact that porn was allowed on VHS wasn't a failure of the Betamax technology.
Preventing key-jamming on typewriters is not a failure of Dvorak.
The technology does not matter, the real world decides. Right now, there is no reason for people to care about IPv6, other than when it's the cause of issues.
