BIf a copy of the downloaded file is redistributed or used in possibly other ways that infringe on copyrights, THAT I could understand, but suddenly making the act of just downloading the file (assuming it is made legally available to the public). But if the downloaded file is analyzed by some software and then thrown away, I don't see how that is infringing copyrights, more than say downloading an image to decompress it and scale it to display on a screen (then throw it away once it is no longer needed).
