1) So how come this important limitation isn't mentioned whenever
someone says "the goal of the ODbL is to preserve the share-alike
provisions of CC-BY-SA"?
2) The whole point of being not-PD is that we can import the
improvements of downstream users without them giving us an explicit
licence. But PD would give us exactly the same thing as you say ODbL is
giving us - incompatible on import (you can't force people to allow you
to use their data) and compatible on export (you can combine it with
ODbLed data, or even any data, from other sources).
How is the ODbL better than PD (or PD-attribution) in terms of allowing
us to use data from other people?

You may not think this is a bad thing, but it seems that rather a lot of
people on this mailing list do.
The position seems to have changed from "if we go to ODbL rather than
PD, we preserve share-alike" to "actually, we don't, but share-alike's
not important anyway. Go get all the data again! It won't take long."

Why are we not using a scheme, used by most open source projects, where
every user of the software/data gets a licence from each contributor?
Why do we need this intermediating third party?
