I know it sounds like a glaring loophole that ought to be illegal, but
I have yet to see a paragraph of CC-BY that prevents me to :
* Use the CC-BY material to create an adapted work
* Release the adapted work as PD with attribution (using PD because
I'm not allowed to place additional restrictions)
* Use the PD material to create a private work.

Of course you expect that in that process, only an insubstancial part
of the original CC-BY material would be left. But "insubstancial"
isn't legaly defined, so an unscrupulous user could get unrestricted
access to a lot of data this way and still stand enough of a chance in
court that nobody would bother attacking (especially considering the
fact that CC-BY licensors probably do not care as much as CC-BY-SA
