As has been pointed out, I was referring to Geocoder's rates. I had the same confusion though. The request for donations certainly makes it seem like they are beneficent, but they are themselves selling the data. Not that that's legally or morally wrong (certainly not) - it's just a different position to be in.

They are only selling it if you want it without the ODb licence. I.e. you don't want to share-alike or attribute.

Seems perfectly reasonable to me.

He was referring to Geocoder. Geocoder sells their database for commercial use for $500.
