Um ... IPv6 CONTAINS (and is therefore backward compatible with) IPv4 addresses.
The first segment of an IPv6 address (up to the first dot separator) is a hexadecimal number that represents any of the IPv4 address from 0.0.0.0 to 255.255.255.255, so all IPv4 addresses can be accessed in IPv6, and all IPv4 addresses have zeroed attributes for the remained address segments.
So it is completely fallacious and just plain scaremongering.
Really, don't journalists have to check their sources, like ask someone who has READ the IPv6 standard? It's only been published for about a decade.
