My understanding is that I upload data to OSM with a CC-BY-SA license. I 
don's give OSM the ownership of my work, I just give OSM the right to 
use it according to this license.

The fact is that some people thinks each user hold copyright on their 
works, while others thinks that all rights on uploaded things are given 
to OSM.
   -> This is a thing that has to be clarified by the OSMF ;)


IMHO, we should use a license that enforce attribution to each 
contributor when talking about "raw data" (planet.osm, REST API, etc.), 
but also allow to attribute derivative works as a raster map to OSM "as 
a whole" (ie a place where you can find the raw data (think about source 
code) with correct attribution).
And also, all of this should be discussed on legal-talk.
