Think different: Those champions of creative freedom, Apple, are
revisiting the golden age of look-and-feel lawsuits, this time
pushing to
suppress an open-source MacOS theme editor. Their rationale is that
it allows users to create knockoffs of the MacOS X Aqua theme and other
proprietary themes. And, presumably, "because we can".
Though the latter part may be dubious; the developers of the theme editor claim
to not have used any Apple code, and the theme format (just a file with a bunch
of resources) is not copy-protected or encrypted in any
illegal-to-reverse-engineer way, having been devised before the DMCA and its
ilk. (Next time, Apple may well encrypt such file formats by xoring them
with "TopSecret" or something; it'll be piss-easy to crack, but doing so
will nonetheless be enough of a crime to get software pulled.)
