Steal (ie claim ones work as ones own, or deprive said owner of content from any monetary return) is a universal constant.
However,
different countries can have different definitions of what constitutes an illegal activity in this regard.
For example:
Here in Canada, I’m allowed to rip a CD to MP3 and put it onto a MP3 player. I’m also allowed to burn a copy of that CD for backup.
However, if I were then to give that CD or Mp3 file to my friend, it would be considered illegal.
Unless I’m mistaken, in the USA these activities (ripping and burning a backup) are considered illegal under the DMCA.
