The tracker is for client connections to Google. To impact that graph AWS customers would have to, en masse, decide the $1/m charge is worth losing half their current users over and then the users and ISPs would have to scramble for IPv6. The more likely story is places using AWS pay 1$/m for a public address and use private/IPv6 internally. I.e. an incremental step, not a revolution in the chart.
