According to this article: ‘The gpl-violations.org project has
uncovered and resolved violations of the GNU General Public License (GPL) in
the Austrian electronic health card (e-card) system.

Specifically, those license violations originate by SV-Chipkarten Betriebs- und
Errichtungs GmbH, the company in charge of setting up the Austrian electronic
health card system…”While there is nothing wrong with using GPL licensed software in commercial
products, it is only permitted under certain obligations, such as passing
on the license agreement, and making available the full corresponding
source code”, says Mr. Harald Welte, Linux kernel developer and founder of the
gpl-violations.org project…’ Thanks to Tim Churches on the OpenHealth list for this link.
