ODbL *is* share-alike for databases, with attribution.

What it isn't is share-alike for produced works.

Even BY-SA doesn't cover absolutely everything it touches. It doesn't 
cover collective works, for example. This may not matter to you or me 
but it is controversial for photographers when their BY-SA work is used 
to illustrate a non-BY-SA article.

Making mash-ups easier and not excluding incompatible data sources in 
what are now called produced works has always been a strong goal of the 
OSM community that I've encountered. ODbL achieves that without 
sacrificing share-alike on the *database*.
