This is called a free rider by economist.

And of course, this is a network, and subject to Metcalf's law, so lack of
deployment actively hurts all those who have made the investment in ipv6.

Simply: buying ipv4 not only feeds the global "digital divide", it actively
hurts those that are trying to make a more inclusive global end-to-end
internet.  Users dont know or care about ipv4. Great businesses dont make
decision on narrow near term shallow business cases.

 business cases are just one of many tools.
