Yes, yes, but you can't stop people downloading it from OSM under the
CC-by-sa license.

Once we get attribution straight, the foundation will have a
non-exclusive irrevocable license to the data, saying that they can call
it Open Street Map data, rather than your data (so that users of the
data don't have to credit all contributors, they can just credit OSM),
and to release it under other licenses than CC-by-sa in time, e.g.

* To drop the SA requirement on derived data in exchange for source data
being made available (like the GPL), so if you publish a book featuring
OSM maps, you don't need to make the book CC, but you do need to make
improvements to the maps available to the project for integration into
the main database.

* To let your data enter the public domain earlier than 70 years after
you die - perhaps 5 years after you enter it. With thousands of
contributors, tracking 70 years after they are all dead will be
impossible, and by then it is probably that the time will have been
extended anyway (it gets extended every time Disney's early Mickey Mouse
films are due to come out of copyright)
