you're referring to share-alike on the images? the proposal isn't 
suggesting removing share-alike on the data, it's suggesting adding it.

i've already stated my argument for removing share-alike requirements on 
the creative output of other people. you clearly don't think it is 
"good". ;-)

being able to use images of our own geodata rendered by other people 
isn't important to me. what is important to me is that the geodata 
itself remain usable, open and free.

the current voting includes a survey, one question of which is how do 
you feel about "requir[ing] maps, map tiles and other items created from 
OSM data to be available under a fixed, viral license." you probably 
want to choose "strongly want" for that.

i'm pretty sure the stylesheets aren't a database. even if they were, 
they're an input to the renderer, not a derivative of the OSM data, so 
they wouldn't have to be released.

that's your point of view, but i've always felt that the data is far 
more important than the map for two reasons; i can recreate the map from 
the data, and a lot of effort goes into creating a really good map which 
i think should be rewarded.
