That's why I like debian. My philosophy closely aligns with theirs. If you don't do anything to change it, a default install will be all libre. If you want proprietary software, they don't make it needlessly difficult to do so, but you have to make an active choice. You won't be surprised by proprietary software.
...Debian does very little setup, and some things you expect to work, won't. It isn't hard to make it work, but it's hard to get the answer if you don't know the question, and ubuntu eliminated that.
Ubuntu drifted away from what I was interested in. More changes to the default install, and adding special ubuntu stuff that did the same thing as standard stuff did, and it made sense to go to debian.
