At least if you’re a big company and you want to violate it.
“The OSM Foundation has made informal contact with staff at Apple and, in addition, one of our volunteer mappers who is an iOS developer spoke to people at Apple. We believe it was the latter that precipitated adding the attribution – it’s great to have such an active and engaged community!
Completely ignored in all of this back-and-forth has been the fact that the CC attribution license is a license for things that are copyrighted, and that if you make copies without following it, you are infringing. Depending on the way Apple has parceled up the data when developing iphoto and the mood of a court, that would be statutory damages anywhere from the low millions to the high tens of billions.
Oh, and distribution of copyrighted material worth more than $2000? Check. For personal gain? Check. In interstate commerce? Check. Apple management and the engineers involved in the project have pretty clearly met the predicates for the criminal law involving piracy for profit.
But none of that matters these days unless you’re some dweeb downloading songs or your favorite movie.
