@sally @adachi The stage3 archives alone are free by default, but that's primarily only because they don't come with Linux or much else.

The default "@FREE" license set approves the nonfree Artistic license by default - so you need to set ACCEPT_LICENSE="-* @FREE -Artistic" yourself to make portage accept only free software by default.

All the Linux ebuilds they provide are proprietary versions of Linux, incorrectly marked as LICENSE="GPL-2" instead of LICENSE="GPL-2 no-source-code".

It is almost certain that there is other nonfree software with an incorrect LICENSE too.

Software that respects the users freedom doesn't encourage the users to install proprietary malware by filling the ebuild tree chock full of proprietary software.
