Also, if we really cared about share-alike, we would have it apply to
"produced works" - that would encourage companies to give back.

Then why mention produced work, since ODBL and cc-by-sa both encourage
sharing the underlying data?
Share-alike of the underlying data is a separate issue from share-alike produced works (obviously). I am aware that ODbL doesn't do produced work share-alike because certain parties want to layer proprietary data with OSM data. I am saying that share-alike produced works would also encourage the sharing of data. Any data that is encorprated into a share-alike produced work can then be rolled back into OSM, not to mention making the rendering and colours available for reuse. This is the intention of the current license (although how effective it is is a separate controversy). What I fail to see is if share-alike is good one one case, why not in the other?
