That's not exactly the argument.
You can reverse-engineer the produced map tiles. But one
interpretation of the ODbL (which I find to be persuasive) is that any
significant extract of data which you obtained from such
reverse-engineering would be ODbL, to the extent that a) it's
copyrightable; b) it's protected by database rights; or c) you agreed
to the ODbL.
