No; it is the decision of whoever makes the produced work whether or not 
he will let you take it and do what you want. He *can* publish his 
produced work as a PD work, or licensed CC-BY-SA, or under a proprietary

The creator of the work has the same freedom in imposing terms on you 
that he would have if he would not be using OSM data. (Whether or not 
the creator of a work can keep you from deriving factual data from an 
image is probably different between jurisdictions.)

A produced work is only a produced work if it stops being a database. 
The exact definition is somewhat murky and will have to be fleshed out 
more, but anything from which you can extract the same amount and detail 
of data as you could from OSM directly is certainly not a produced work.

I believe so, but there are many in the project for whom even the 
proposed ODbL is already going too far. Some would like to force 
anything that remotely comes into contact with OSM to become "free" 
according to their respective definition.
