I agree that the terms are relatively toothless. However, all license terms are toothless. Is anyone suing if ADNI data do not have ADNI as authors? [As a reviewer, I�ve rejected a few papers that didn�t follow protocol, but there is always another journal].

I think the statement that contributors want to make is that de-identifying data break the trust that is placed in us as researchers. So, other researchers should agree to those terms.
