"The number of people using Linux systems is increasing every day, and many of these users depend on the security of these systems in critical ways. It's vital that we do what we can to avoid their trust being misplaced."

This, a thousand times over. Security and privacy concerns are ultimately among the make-or-break points of any major platform, and Linux needs to pass this with flying colors, especially as it grows ever closer to the ordinary user who is finally considering replacing Windows.

Even without the point about more users wanting to replace Windows with a Linux distro, it makes harder to argue that "ATMs should run Linux instead of Windows", if Linux is falling behind in security. Also, ATMs should probably run OpenBSD.

Mainly, the PC inside ATM should not do anything remotely security critical. PC-based ATM platforms are actually designed around compartmentalization and in ideal case the PC should only draw UI on screen, handle some subset of input events and route encrypted messages between other components of the ATM (whether it's implemented in this way in actual deployments is another issue).
