You're probably talking to the wrong person because Frederik is one of
the PD advocates and just gave an answer to your question.

But I like the Share alike rule and if you use the data produced by
osm, osm wants to be able to use the result under the same license.
Otherwise the situation may become like with the Map_Features
cheat-mug, it's only sold locally, but at the same time nobody else in
the world can produce identical mugs.

In this case however I'm not sure, the CC-By-SA is not precise about
what part of the work is share alike: only the data, or also the style
you used? (It's not precise because it wasn't made for data
talks about the case where you're using only the data, not tiles, and
says that then you need to state "map data CC-such-and-such" which
implies that the rest is not necessarily CC-such-and-such.
