I started mapping because I couldn't use commercial maps, if I license
my maps under the ODBL then I will not get to make a copy of the maps
I've created myself.

Anything that was CC-By-SA is always share alike, the ODBL leaves that
SA philosophy altogether. I don't see why people with the resources to
render Openstreetmap data should get a benefit, this will create a
very big divide between the ones that can render/style the data and
those who can't.

Since how the map is rendered and presented is so important,
especially for data quality, I don't want random companies controlling
the representation of my Openstreetmap data.
