As a great supporter of free software, I always try to reduce the amount of non-free stuff on my harddisk. This time, I replaced the non-free unrar (unpacker for the rar-format) with a gpl-version of unrar. I already added an ebuild to portage, called unrar-gpl.
The only non-free things left are some Browsers (Opera, Netscape 4.x) I have installed to test my webpages and some old games I like to play in emulators (e.g. Monkey Island).
