Actually it wouldn't.

The OSMF has a binding contract with a large number of mappers, 
representing a substantial part (actually the majority) of the OSM data, 
that specifies CC-by-SA 2.0, ODbL 1.0 and DbCL 1.0 or a vote on a new 
license. As I understand it, the automatic upgrade clause in CC-by-SA 
2.0 would only be effective for a licensee (that received the data under 
2.0) that wants to distribute the data under a higher version.

Since the pre-CT terms can at least be read differently than the current 
OSMF interpretation, it is a least open to dispute if the same wouldn't 
apply for mappers data that haven't relicensed yet



PS: in an hour or so, we will be over 10'000 explicit acceptances of the CTs
