So you mean the data will become sort of "public domain"?

Well, then there is question: what is worse?

1. Have all the data, but risk someone "abusing it"?
2. Or force the license change, therefore enforcing the share-alike
rights correctly, but tossing some data away?

Note that if cc-by-sa is somehow abusable, anybody that want to abuse
the license using some loophole will simply grab last dump srill
published under cc-by-sa instead of the new license - and then abuse
the non-enforcability of cc-by-sa to databases.

As for the possible data loss - since new license is basically still
in spirit of cc-by-sa we can assume that most users will agree to
license change, if we can contact them.

So if we assume we will contact everybody who has logged/uploaded data
at least once in last month and we will fail to contact the others -
how many data will be removed?
