Control of creativity

For a few years now the media companies have been going nuts about copyright protection. This article compares the differences in control over creativity in the fashion and the media. Why is it that Sony, for example, goes nuts if you sample a few seconds from one of their artist's tracks, but if you copy someone's clothing designs (as Topshop, H&M, etc. routinely do) you get, if not applause, at least no negative repercussions. I don't have a good answer, but I know which model I prefer.
