The OSM Foundation can change the license under which OpenStreetMap data
is distributed. A 2/3 majority vote of the active contributors is
necessary. Even if you voted against such a license change, the data you
uploaded will be distributed under the new license because you agreed to
the Contributor Terms when either joined them or during the last license
change. If we import third-party data which is not licensed under the
OSM Contributor Terms, we have to run the Redaction Bot on the import if
the license of the source is incompatible with the new license.

You can read the OSM Contributor Terms at
