I don't think the general motivation for share-alike is that you want to 
be able to gobble up into your database whatever other people add. You 
just want it to be free for everyone to use!

Anyone could set up a database where he imports all of OpenStreetMap 
*plus* every OSM derived database anyone has ever made.

You seem to be overlooking the fact that the contributor agreement is 
only used inside OSM; if anyone is ever unhappy with that, they can 
simply create a derived database by loading the full OSM database into 
their system and not be constrained by the contributor agreement any more

I am starting to be anti-import as well. If there are other datasources, 
let us link to them instead of becoming the bitrot centre of the world. 
But the question is rather academic anyway since there are unlikely to 
be other ODbL licensed data sources.

I thought you were talking about problems when re-incorporating 
downstream additions into OSM. What has that got to do with having to 
get data *again*?

We have established - well 80n has challenged that in his post this 
morning but I still maintain that it is correct - that most OSM 
contributors have nothing that can be protected. Not by copyright 
because it is factual, and not by database law because it is not a 
database. Why, as a user of OSM data, would I *have* to get a license 
from some contributor?
