Exactly. But it also true that if you offer something unlimited you need to add reasonable limits / throttling so that pathological and cheater do not destroy experience of others. Amazon Drive might be able to bandwidth limitation for users which are abusing the system but as I far as I understand they just route things to Amazon S3 so bandwidth limitation is probably hard for them. Also they probably do not want to add bandwidth limitation for people who use Amazon Cloud Drive for photos and movies. Not 100% sure but I understand they position. And I read on redit how people started moving data to Google Drive thinking everything will be super fast - but Google already have bandwidth limitation in place.
