I dunno, there just never was a conviction or even a legal case for developing a crack. Since the DMCA however, there has been the infamous Adobe ebook case, where a russian firm that developed a braille program for blind people, got accused of breaking the DMCA. They circumvented the copy protection in Adobe ebooks so they could write their own interface to convert those ebooks in braille. So you see how evil the DMCA really is. If a similar law passes here in europe, then we'll be in similar trouble
