I'd say that it's not that there's some gain causing people/organizations to be obstructive, but rather that IPv4 and its address shortage simply isn't a problem for the influential people and organizations, they're doing just fine and for them there is nothing that needs to be fixed; IPv6 is needed by "someone else" who can be safely ignored with no noticeable effect to the bottom line.
