There are some interesting issues raised in here, such as:
"Germany has raised a number of fundamental objections to the idea of OER. They question whether a lack of digital content prevents learning, particularly in the case of people with low qualifications, and whether well-educated people will benefit the most from OER. Furthermore, they ask if there are any sustainable business models for OER and suggest that there are questions of standards, quality, technical interoperability, and legal questions concerning copyright that have not yet been solved. The issue of copyright is widely discussed in Germany in reference to the ongoing Open Access debate."
