alternate conclusion,
If you believe, like many data donors, that the attribution must be preserved,
then a licence which incorporates the viral provisions is necessary.
If you believe that the data should be completely freely available then
neither ODBL nor CC-by-SA is appropriate, and a CC0 licence should be
considered.
If your major concern is that improvements to the data should be fed back into
the common pool of data, then CC-by or CC-by-SA would be suitable (and maybe
others)
Please leave out very emotive language like "dangerous" and unproven
assertions like "most of us" without defining "us". I realise that it was
headed "personal conclusion".
