Proprietary garbage dump?
The crappy part (as stated, for Windows) I get.
I don't understand the proprietary part, unless you're going for the literal meaning of that it's owned by a company, which is true for almost any non-freeware software application. It was also not originally developed by Apple, but was purchased from Cassidy and Greene, which makes great software.
What about iTunes is proprietary when you can use a variety of formats for your media, the majority of which do not involve DRM. Note the following variety of choices: iTunes 8 can currently read, write, and convert between MP3, AIFF, WAV, MPEG-4, AAC, and Apple Lossless.
iTunes can also play any audio files that QuickTime can play (as well as some video formats), including Protected AAC files from the iTunes Store and Audible.com audio books. There is limited support for Vorbis and FLAC enclosed in an Ogg container (files using the FLAC container format are not supported) or Speex codecs with the Xiph QuickTime Components.
The latest version of iTunes (Win/Mac) supports importing audio CDs with the default iTunes standard file format of AAC at 128 kbit/s, but users can choose from 16 kbit/s to 320 kbit/s constant bit rates (CBR) in either AAC or MP3.
The Windows version of iTunes can automatically transcode DRM-free WMA (including version 9) files to other audio formats, but does not support playback of WMA files and will not transcode DRM protected WMA files. Telestream, Inc. provides free codecs for Mac users of QuickTime to enable playback of unprotected Windows Media files.
I'm not seeing the limitations here. Not wanting to fight, I'm just not seeing it.
