I've talked to a mail admin from one of the companies involved in "Email made in Germany" once about it, and his reply was basically that of course it was marketing, and of course the techs had the idea to enable TLS in the drawer for years.
But at their scaling, enabling TLS means a lot of additional compute power, and due to that marketing campaign they now finally got the budget to install the additional hardware and enable it. Before, there was no business value that justified to spend that much more to get an - to the outside observer - unchanged product.
