Apple used to bundle demo apps and games with their computers. I for example remember getting a demo of a Tony Hawk skating game and a couple of other apps with an iBook.
iTunes isn't crapware on OS X. It is on Windows though, I think mostly because Apple doesn't want to put too many resources into iTunes on Windows.
iTunes on OS X runs better than any other music apps (that are not command line music clients like ncmpcpp) I've used, and I've used a lot. On OS X, I can't see why people would call it bloatware/crapware.
