That's not true at all.. transcoding a video and uploading it to a video sharing site is editing the content and misrepresenting it and something it's not. If the quality of the transcode is poor, if the audio quality has been trashed or segments have been pan and scanned, cut-out or otherwise modified, then it's being represented in a manner that the author may not have intended or desired.

Warez releases are often ripped, modified and repackaged in a way that may or may not look or act anything like the original.

Copyright holders have the right to decide when, where and how their work is displayed, consumed and presented, but the public at large don't seem to give a damn anymore.
